What danger? Because they said now they’re responding to legal requests/monitoring? Your chats are no less private there than they were before. Not saying it needs to be telegram, but my point is that if you have a large group chat then it is the same as having a public community and you might as well approach it as such. Everyone in that group can share the contents and you should expect that they do. Especially if it’s a group that you constantly add new people too. Don’t larp about privacy is all I’m saying. If you were using telegram then it wasn’t private anyway.

I think the difference with simplex and oxchat is that while the members of the chat can share the information there is not a large central entity that can compromise the privacy of any group. Telegram has fantastic ux and features along with a great network effect but I'm happy that whatever is going on is creating enough disturbance for people to start trying out other options.
It’s very easy to social engineer your way into being accepted by someone in a large group, and that gives you an “in.” I can understand it if the concern is a central entity being able to shut the group down, so I’m not saying looking at decentralized options is a bad thing. But any large group chat/channel might as well be a public forum from a privacy standpoint.
