> Re. WhatsApp, Signal, Telegram and iMessage are all apps you run on your phone. And if you can read the messages on them from a website (as you can if you turn on a feature for imessage), then the admins of the service also have access to your messages.

Not true. Web clients for Matrix are open source, and you can self host them if you are afraid of the default host trying to inject spyware to the page

I mean, the website admin in that case can still access your messages. It's just that the admin is you.

That's true. Though I guess that when my parent comment referred to "admin", the were referring to the admin for the homeserver (the one routing the messages), which is different from the one hosting of the web client.

This is why services like Matrix and Signal open source their client. Because for security minded people, securing the client is much easier than securing the server.
