You're 100% correct on website, we need an upgrade. We have someone starting soon to help and we'll show them this thread.
A couple of notes:
1. Push notifications are free. Paid is if you want to use Mattermost key for encryption (we choose not to encrypt things for people we don't know, but we document how they can do it themselves): https://docs.mattermost.com/overview/faq.html#are-push-notif...
2. Our intended users are organizations that need to deploy communication behind their firewalls (no 2fa from us needed) and can't use SaaS, e.g. manufacturing, banking, healthcare, public sector, security companies, companies with very strict non-disclosure agreements, etc.
Logos on our website are examples: https://about.mattermost.com/
PS: I read about HearthSim, you're running a really cool company. If you're ever in San Francisco for GDC, perhaps we could meet in person.
