Users should be aware of anti-feature of packages. It is best to have anti-feature tag in anti-feature packages so that user know which program has anti-features; Like F-Droid. Also, user should be aware of anti-feature during installation. And wherever this awareness is needed...
An example is Telegram, Telegram is a program that user connects to a proprietary server, and users who know less about computer softwares, are not aware of the anti-feature.
