The surprise is more at the (EDIT: brazen) pathological lying.
In fact, I would consider changing goals publicly to be better than not following the goals.
Wired claims OpenAI’s “reports to US tax authorities have from its founding said that any member of the public can review copies of its governing documents, financial statements, and conflict of interest rules.” That was apparently a lie.
> Changing their goals is also not lying
Changing a forward-looking commitment is. Particularly when it changes the moment it’s called.
I don't know if I'd put this in terms of a "lie" or not, but OpenAI's stated principles and goals are not backed up by their actions. They have mined other people's works in order to build something that they purport as being for the benefit of mankind in some way, when their actions actually indicate that they've mined other people's work in order to build something for the purpose of massively increasing their own power and wealth.
I'd have more respect for them if they were at least honest about their intentions.
