I think it's organisational incentives, not tech per se. TL:DR; Brand risk, and the FAANGs are not as hungry. Google and MSFT are wary of deploying tech that gets caught saying super racist or nazi stuff (MSFT have been badly burned before) and they already have big income streams, they didn't feel strong pressure to "ship". OpenAI has less to lose, more to gain and people are more tolerant of janky cutting edge products dressed in "startup" branding.
