Top comment: Discussion on Moraes, not Musk
Second comment: References Elon/Elon's past compliance, some replies bash others support the policy
Third comment: About how companies will have to deal with more international events like this
Fourth comment: Mentions X but not Musk, some replies get into Elon back & forth though
Fifth comment: A pretty plain Musk bash
Overall sentiment of Musk certainly wasn't in overwhelming favor of Musk but the top commend and many other threads were focus on Moraes or things other than Musk. Of those that were, most seemed to mention him to bash but certainly not "everyone" bashing him by any measure of the word.
I think you see a lot more "dunk" on posts when it comes to the general political area around "Rumble" or the like. Personally more dunking on than I think is often fair as well, even though that direction is not my personal leaning. Musk himself is actually much less of a downvote trigger, even though he's got a way of getting mentioned way more often than he should in threads (like how the comments on this article have become largely about him when it's about Brazil and Rumble).
Or perhaps you're right and people really have no moral principles and just say whatever is more convenient at different times. That's a scary thought. I choose to believe in the first alternative. Plenty of people complained about Moraes when he was bashing Musk.
