As someone in tech looking for a role, I agree, though there is some utility for big tech companies where compensation data is available elsewhere. By looking at the upper bound of the salary, I can reasonably infer the level of the role. For example, level 6 SWE roles at Meta show an upper bound of $241k and level 7 SWE roles show $289 (or thereabouts, IIRC).
It's still of limited utility though, since one has to still use an external source to identify bonus percentage and possible range of equity values.
At the least, they are helpful for people who are not “in the know” for which types of labor are selling for the highest prices.
Maybe non native language speakers, immigrants, the immigrants’ kids, etc. more transparency in labor prices is helpful to at least the people earning less than the highest earners to show them where they can earn more.
