I use Slack, WhatsApp, Discord and Facebook's Messenger. On my computers, rather than installing dedicated apps, I've always just used these services' browser versions. It allows me to block ads with my browser's ad blocker and modify the UIs with other extensions that I use.

But in terms of privacy — and more specifically, in terms of what the service has access to outside of their own walled gardens — is there a difference between using these services through a browser or their dedicated apps? I use both Windows and Mac computers, if that makes a difference. My browser of choice is Firefox and I run the services in their own containers.

On my phone, I just use the provided apps and get notifications that way. I am well aware that most of these protocols are not great for privacy to begin with, but I'm not currently looking for other messaging systems.

I just noticed that when I sent an invite to family member over SMS it never arrived. After experimenting it looks like if text contains "tildes.net" it is filered. This also happens with another family member's phone. It is weird why would those companies want to filter it.

I also checked and the message didn't show up in spam & blocked. Does anyone else observe the same thing?

To be clear, Matrix as in the communication protocol. Curious if anyone has any recommendations for communities there. Personally I am mostly in the NixOS space, since that is the official chat for issues and questions.
