@m you might want to double check on Matrix though:

Matrix is a decent IRC replacement, but a secure messenger it is not. I've always felt that encryption was bolted-on as an afterthought in it and that that will lead to tears, and as time goes by I get more and more proof of this.
@rysiek
I have recently and my experience was quite shitty and it is so bad that i cannot use it.
I posted about it a bit, the only thing that somewhat remotely is usable for me is FluffyChat and they do not support a lot of great accessibility stuff i want, like voice messages that you can convert to text easily, send quick videos, send your location for the next hour or have a "send without sound/ send when online" features.
And somehow it seems super slow in comparison with Telegram.
