IMHO levels.fyi, and to an extent Blind, are both semi-disrupting this. (You can see Glassdoor considers Blind a threat bc of their Fishbowl offering).

Both blind and levels are missing somethings though. Levels was just comp for the longest time but their forums are an attempt to move into this space. Blind has other issues with their user demographic and moderation imho - its a little too toxic at the moment to compete at the highest level. Theyre also too focused on tech and software careers alone.
