> He didn't just say he "wasn't happy about it," he also said "I don't blame them." You're right, it's not apologizing, but it's exoneration.
Insofar as "I don't think they're guilty", yes. This is a slightly lower bar than "I think they're innocent", because the former covers cases where you're unsure. Maybe the person you replied to actually thinks robinhood is innocent beyond a reasonable doubt, but that can't be confirmed via his comments.
> I think of it more like when a cop gets away with murder in our legal system. Did he commit a crime? Well, technically no, because our legal system said so - but I still feel comfortable calling him a criminal
This analogy only works because you can presuppose that the cop is guilty. It breaks down when you can't. For instance if you only knew that he shot and killed someone. Maybe he acted in self defense (the actual kind).
My understanding of the situation was that robinhood was forced to restrict trading for meme stocks due to increased deposit requirements on them. If they couldn't come up with money to meet deposit requirements (due on the day of trade), then they have to halt trading. Meme stocks like GME had disproportionately higher deposit requirements, so restricting those stocks would allow them to continue operating with the smallest impact. If those stocks weren't restricted, they would have burned through their cash/credit they had (to meet deposit requirements) and would have to halt trading anyways.
Now, this is what robinhood is claiming, and I can't verify every single detail of this story (although some elements were independently confirmed, like the deposit requirements going up). Maybe robinhood had a boatload of cash/credit on hand and could have easily met the day/week's trading volume, or maybe it would have been close and they didn't want to risk it, but you think they should have went ahead anyways. In any case, the whole situation is less clear cut than the standard villain narrative of "they shut down trading because the hedge funds told them to". More importantly, there's enough wiggle room for differences of opinion that if someone says "I can't blame robinhood", you don't have to immediately accuse them of "willfully absolving others of guilt".
