My main gripe with Signal is that they force-push out multi-hundred MB updates to a multi-hundred MB app, disabling it if you don't keep updating, that sends texts and makes calls. Five gigabytes worth of forced updates earlier, it sent texts and made calls. Five gigabytes worth of forced updates later it'll also send texts and make calls. And every time there's yet another completely unnecessary update that changes nothing in the app I have to go around various older family members and update their phones with it.
