I don't care whether google, ycombinator, airbnb, etc acted out of their own self-interest or not (for marketing, as you say). I don't think anyone should. I'm not naive enough to think they would act altruistically, all I can hope for is that our interests align at least temporarily and they help. Perhaps they could've done more in the situations you're describing, but it seems odd to chastise them now that they are. Would you rather they didn't ever help?
