This judgement is about Instagram, specifically. Messenger pre-dates Instagram (and very significantly pre-dates the Facebook acquisition of Instagram).

> Messenger was never the primary draw of Facebook.

I didn't say it was. Remember, my statement was: ... that people are in the app because Facebook gave out Facebook Messenger

Indeed, I remember using Facebook just for messages. So when Facebook Messenger came out, I used that exclusively.

Now, I've long since moved off of Facebook and Facebook Messenger. Some of my family still use it though, and I've seen it. It's not what it used to be. So, I then expanded on that to say: Then Facebook changed how Facebook Messenger works

> they’re factually incorrect or illogical

So, where's the factually incorrect or illogical argument?

The final straw for me to move off of Facebook was Cambridge Analytica. Once I realized how terrible not just Facebook was for not only permitting that kind of shit, but practically inviting it as a feature... that was very telling. And I've since stopped using nearly all social media, present website excluded.

I think this really only becomes an issue if the changes you made to your app is in some way affecting democratic elections in that country (and in that case, seems well within the purview of legislation)
