Yes, it sounds like it's close to the (legitimate) bogeyman of government intruding on it's citizens for nefarious control reasons. But these are public posts - intentionally posted publicly to persuade others — not private communications.
We should not be unilaterally disarming and blinding ourselves to what is happening the public sphere.
If you want a self-determined life in a society with a self-determined (i.e., democratic) government, then we must always be better armed and better prepared than the bullies and authoritarians. If not, they will steal our lunch and our government every time. Awareness of what is happening is just part of being prepared to keep our democracy.
