This statement is patently false. Go look at the top paying companies on Levels.fyi for the last 2-3 years. A good portion are not major corporations but rather VC-backed startups. For a while there, Roblox and Robinhood were the ones offering insane compensations and much of FAANG (expecially AA, excluding N) were falling behind.
This also says nothing of the (what I would consider) tier 2/3 companies still offering over $300k TC for senior (5+ yr experience) technical talent. There are _even more_ more well-funded, semi-unicorn startups offering base salary $200k+ plus equity in their startups. In my last job search alone I found 3 of these companies which you've probably never heard of.
The competition for _technical_ talent is fierce.
