Free software is like democracy. Sometimes people elect dangerous idiots.
In free software projects, if the users don't clearly value freedom, then companies add non-free plugins, non-free dependencies, and non-free websites to the free software systems.
I have the source and the freedom, but I don't have the time to reprogram my desktop. I have to rely on the users in general signalling to the developers that anti-privacy features and non-free dependencies are not what we want. This is worlds better than the situation of a user of proprietary software user, but it does take some daily effort.
