Yeah, it sucks and the teams has acquired the reputation of sellouts, but in practical terms, does it really matter?

It looks like there's a new team with equally good or better models announced on HN every few days.

OpenAI looks like they've ingnited the field like no-one before, then did a smart move of selling to a company which has a lot of money but doesn't always know what to do with acquisitions, while at the same time that sale didn't hinder actual open development (by other teams) one iota.
