What would Wall Street care? All that matters is that a company goes public while there is still some (perceived, at least) upside for retail investors. If the main company of going public is to give investors / employees liquidity, then of course they are going to bomb. If the company has real upside, then it will be fine.
The problem here is that of pricing (and nothing more).
Wallstreet wants to pay X, but VC wants 5X. This is why the "window" is closing.
