The main issue I have with these sites is that they are relatively pointless. The really only are able to cover low and mid level position salaries. Those salaries are not generally very elastic anyway and you can get pretty close to the the salary info from public stats anyway. This makes the site pretty much useless for those jobs.
If you are the Director of AI/Machine learning (or CFO or whatever) at some company there are probably only you or you and one other person that ever had that job. By providing the salary you are outing yourself anyway and risking some sort of action against you. Anyone looking to move into these good jobs has no use for the site either.
This is the real problem glassdoor had/has and why it will eventually disappear or become nothing but ads or headhunter style site.
