I personally know some of those people. They are basically being forced by their employers to post those things. Additionally, there is a ton of money promoting AI. However, in private those same people say that AI doesn't help them at all and in fact makes their work harder and slower.

You are assuming people are acting in good faith. This is a mistake in this era. Too many people took advantage of the good faith of others lately and that has produced a society with very little public trust left.
