They show ads in public channels with high amount of users.

While I rather use more secure apps for following public channels, sadly they don’t exist on other platforms.

I believe not, the foss release will make the app run in the background to check for notifications.

But unless we are talking about very few non-profit news organizations, you have to choose one of them.

The question assumes that you will have to experience whatever you choose, so without ad blocking, what would you choose?

No what?
