It's funny that in under a year we went from Sam Altman publicly saying that OpenAI was going to "steamroll" startups that were building products within its blast radius to now offering multiple billion dollars for those same startups.

My uninformed and perhaps overly charitable interpretation: he warned them they were going to be steamrolled, they built their product anyway, and now OpenAI is buying them because (1) OpenAI doesn't want the negative publicity of steamrolling them all, and (2) OpenAI has the money and is a bit too lazy to build a clone.
