I didn't read a complaint about premature acquisitions in between these lines. Though sama may feel that way about certain promising startups. I don't know. I think he says what he means here; these largest companies "have powerful advantages that are still not fully understood by most founders and investors." And it's compounding. Given that, I think being a bit more cautiously considerate and unpresumptuous about these issues as well as on any views or insights one might have makes a lot of sense. Basically this is a shitshow still in progress. There are startups that in hindsight had a too early, under-valued liquidity event. And there are many many startups that turned down acquisition offers never to see that many zeros offered again (I think Pebble just sold under these conditions). Whoops. Also don't forget how a startup's risk profile and internal planning changes dramatically when/if an acquisition offer is turned down. Too early is not the problem here. If Amazon or FB wants to buy you and you say no, well good luck. Competitor risk is a real business cost and it can weigh you down no matter how fast you may be growing. If anything I see uneasiness more than complaint as the playing field has warped where hills are now mountains only giants can cross. The rulebook has changed too, startups aren't even playing the same game as large tech companies anymore. As the letter suggests, startups can play at the fringes and margins, then maybe try to sneak into grown-up business land but this is increasingly, laughably unlikely if you model it. What is more likely is startups miscalculating how big and lucrative their idea is and they are screwed, or they miscalculated how fast and easy Google can crush their prospects once Lar and Serge notice what you're up to. The options are lose now or lose later, with only the rarest of startups as exceptions unless someone or something steps to address the underlying structural realities.
