These are legal and contractual proceedings, with strict definitions of terms by law, not by popular opinion in the hacker community.
"Underlying motivations" of the investors is never a legal factor in any kind of investment deal. That's not something that can be accounted for by any kind of contract.
I would not have guessed that. Why would I need a VC firm to invest a few thousand dollars into a company?
They raised money in the form of SAFE notes, in which case a venture capital firm is created (you can also call it a legal entity or a juridical person) and each investor owns a part of that firm in proportion to the money they invest. That firm in turn will have a contract with the startup company which details and regulates how the invested funds in the future can be transformed to actual shares.
Key difference: They didn’t take any funding from anyone whose values are misaligned with their own
