I completely agree that everyone should use free software. Not for free of course but by donating or straight up paying for it.

That aside, I think your stance is the „vindictive vegan“ approach. While I‘m a newly found fan of veganism, I strongly dislike the „you’re either with us or against us“ approach.

I personally run a matrix server (which is foss, even if it sounds like its second class foss to you) and have it bridged to discord, whatsapp and signal. Why? Because that helps me convert people.

Their reasons for joining matrix:

• You can use one app (fluffychat in my case) instead of four apps
• People on the other platforms miss out if the bridge goes down which shows them its matrix first. With mautrix bridges, the bridge very rarely goes down btw
• their chats will be accessible for them forever if they wish, with backups they can take whenever they like
• no chance the EU breaks their encryption
• no chance for discord, meta or anyone else to sell their data (of course not in the bridged room)

I think there are better albeit more manipulative ways to get people to convert instead of punching them on the nose. Certain matrix only rooms do help, provided they have no equivalent on the other side.

Anyway, have a good one.
