It's 2026 and we have no fully satesfying messenger for blind people.
WhatsApp, well no need to say anything.
Telegram, Image (can't imagine most germans switching) and IOS apps get less accessible e.g. no voice over focusable edit feald etc.
Signal, Desktop client is trash for screenreaders, ignore request to add TalkBack actions to Android apps, accessibility doesn't seem to be a high priority
Delta Chat, Yeah actually not to bad, though no web client through a browser, but as long as there is a portable app for Windows I guess that's doable, not sure atm.
What did I miss?
