I ultimately agree - I'll play Devil's advocate a bit:
Such an attack is referred to as a "long range attack" and is 'solved' by 'finality' in Ethereum, the largest running PoS network. Finality basically means a hard checkpoint. I won't make you say it: finality can of course be changed on different forks, and that's the core issue in PoS.
There is probably some utility in adding friction to such corruption, but that the mechanism doesn't ultimately prevent it and really just adds incentives to controlling it.
Attacks on PoS are more convoluted, but there are more of them and more ways to approach them. I fully agree this fact is lost in obfuscation and jargon.
