@mousebot it's a vc-backed corporation so will never have the user's best interest in mind, combined with full access to everything you do on their platform , and iirc a privacy policy that states they can use all that data for advertising and what not

It's not much different from slack/telegram/many others fwiw

WhatsApp / Signal are still centralized but have e2e encryption so they can only access (various levels) of metadata

Matrix (and XMPP) offer e2e, and a decentralized model similar to how Mastodon has many different instances, that still communicate with eachother
