This is what everyone says. "we know our salary is competitive because we benchmark it against the market". Most benchmarks for tech companies are dogshit though.
Yep I was going to say the same. My recent gig was like this, they paid a consultant firm big money to find out what the "market rate" was, around when I was hired, and when they finished and my boss spoke to me about it, he was like, "well you are way beyond the market rate they determined." My response was, "well are they going to try to claw some money out of my salary" and he kind of laughed and said no.
And turnover here is super high due to salary.
