Far be it from me to defend Y Combinator or VCs in general but IMO the situation is a bit different because of the monopoly (or at least duopoly) power that Apple and Google hold as gatekeepers over the only practical way to sell to iOS and Android device users.

Of course, I'd also assume most or all the people associated with YC were part of the "fire Lina Khan because our whole business model is actually just taking advantage of FAANG acquihire panic" squad, making them hypocrites (in a slightly different way) for helping to prop up these monopolistic gatekeepers and then acting put upon by the results of that.
