If you talk about that stuff, people will dilly-dally with the usual "well I already have too many apps, I'm not sure I want to install one more"
I tell people that the video calls are better (which was true in my experience, back when I still used WA). Instant install
This is wildly untrue on iOS. Perhaps people have 100+ apps. But the rest, not so much.
Anyone new who wants to message me, I simply say "I'm on Signal" and if it's important enough, they go and install it; it's been fairly frictionless, after all how hard is it to download an app and go through the fairly minimal registration process; and for someone already using WhatsApp, "one more account" probably isn't a major concern.
I tried various steps in the past to retain access to WhatsApp for a couple of people who didn't move, by having a work account on my phone, with a second SIM, but a one-click mistake one time gave WhatsApp my entire contact list from the "Personal" sandbox account, and I've decided not to even bother again.
Genuinely curious. I am in WhatsApp groups for my kids soccer teams (who will be there at the game, can my kid drive together with you to the match), my kids school classes (Johnny lost his headphones did anyone see them), my work teams "social chat" (happy birthday, I am at conference XYZ) etc. etc. In your situation, which of the three scenarios applies?
1 - You are not in such groups
2 - You were in such groups, and the entire group moved over to Signal
3 - You were in such groups, but the entire group did not move over to Signal and now you are not in these groups anymore
People on Signal tend to have much less volume of overall messages and groups. For someone on WhatsApp to forward you the invite is a hassle for them, sure, but it is an infinitesimal unnoticeable increment on how many in/out messages they deal with in a day.
As I mention in another thread, people will complain that they "have too many apps" if you pitch Signal as a privacy app. They would install it instantly if you told them the emojis are funnier or whatever. Because they already installed 300+ apps and one more is actually .3% increment ; whereas for your typical GrapheneOS F-droid person, adding whatsapp would be a +15% increase of apps on their homepage.
It's kind of the same with those WhatsApp groups. There will be 1,000 messages in the group this week/month. 3 of those are the actual invite you need, and if you have actual human connections with folks, someone will send you those.
I finally had to install WhatsApp on a trip recently for group coordination, but ensured it didn't get things like contact access, and removed it afterwards.
Kids school may well be an outlier (US), but they send formal communication by email (with an SMS notification or call for emergencies), and the parent group is all on iMessage.
EDIT: re: Work, my colleagues are all on Signal, we have lots of Signal groups to communicate.
And I don't want to go to signal because it's only marginally better. It's still American and still a walled garden (no third party apps allowed, no federation). It's a slightly less smelly walled garden.
> And I don't want to go to signal because it's only marginally better. It's still American and still a walled garden (no third party apps allowed, no federation). It's a slightly less smelly walled garden.
This, to me, is downright irrational. "Less smelly" is better, especially if it takes zero effort (you don't even need to create an account with a password, it just sends you an SMS).
If there was a non-American alternative to Signal, surely I would go for it. But there isn't. In the meantime, Signal is by far the best alternative to WhatsApp in terms of privacy.
Not to mention that there is actually a valid reason to not allow third party apps (spoiler: security). Last time I heard a fork of Signal making the news, it was pretty bad.
A European alternative would be excellent (I'm in the UK), but no such thing exists, that said, Signal's server and clients are open-source and can be self-hosted, or even deployed at scale by a European government/entity if they so wish.
I work in the "secure comms" space, and I have reviewed every line of code in the open-source server (as of the revision I last worked on), and built products on it, and though I can't prove they run the same code they publish, I'm "happy enough" with what I see that I'd use it over anything owned by Meta any day.
In an ideal world, I'd host it myself for everyone I communicate with to use, but without federation that's not a possibility, so given a choice between Signal and WhatsApp, the decision is hands-down Signal.
Over time such verification "decays". People buy a new phone, that sort of thing, but it was a healthy boost in one inexplicable moment.
It's like: should we all go to a vegan restaurant instead of the usual steakhouse because you decided you want to "try" being vegan this Friday night, of all nights. Just try it out another day and let us have our fun, Fred.
If you were not on WhatsApp at all, then it becomes a balance of : tiny per-person inconvenience versus 100% clear-cut decision on your part. Oh you've converted to whatever religion and can't have pork anymore? Now we have a choice between not inviting you at all, or trying the restaurant next door.
That would actually be marginally better. No everyone is on f-ing Snapchat. I'm in Denmark, which like the US is pretty big on iMessage, so originally we where using that. Then my sister got an Android phone, and the group chat obviously broken, because no RCS back then.
Everyone has SMS, Snapchat, Facebook Messenger and Instagram (except me for Meta products). So no one is really keen on adding a fifth app, where for me it would remove Snapchat, bringing me down to just SMS and Signal.
With some people it worked though and we are using Signal for some time now. Maybe it is too much to expect a 100% success rate for switching.
