What ultimately pushed me to leave Matrix was discovering that my homeserver’s admin was using my account without my consent.

In an encrypted room even with fully verified members, a compromised or hostile home server can still take over the room by impersonating an admin. That admin (or even a newly minted user) can then send events or listen on the conversations.

…, I’ve decided to move my conversations over to SimpleX.

For the past few months, the Matrix community has been largely inactive (despite having over 5,000 members), while the Telegram community has remained much more vibrant. This is disappointing given that I have been a strong advocate for using Matrix and have promoted it widely. For some reason, people are not moving to Matrix at the rate I had hoped.
