I logged into telegram today and found that all my data had been deleted because I hadn't used it in 6 months. Like I get why that feature might be desirable in some circumstances but for me, I'm not using end-to-end encryption because I'm sharing state secrets that need to self destruct upon opening - I just don't want the middlemen.
I've been looking into alternatives like Matrix/Element, XMPP etc - it sounds like Element might be easier to get non-techy friends to adopt but it, from my understanding, has a fairly power hungry mobile app.
