The biggest mistake is that people trusted a company that, in reality, isn't that different from Apple. Just because everyone claimed Android as the true open source alternative to iOS, when only AOSP was that.
Apple (under Jobs) sold themselves as counter-culture, they used popstars (unironically), and design, to sell the idea that if you were your own person, or followed fashion, then you bought Apple.
I think the goodwill from those days still provides the foundations of their cultural position now. Although they chip away at those foundations.
OpenAI looked like it could follow Google's early model, until it didn't.
