As far as I can tell, what's upvote heaven is complaining about how nonexistent bad comments get lots of upvotes. I don't see any comments in this thread that meet your description, while the top is mostly comments explaining why this move makes sense. There are quite a few kneejerk "the US is evil" comments, but it's not about playing nice, it's about thinking the US government is the devil and SpaceX is sullied by the association. I don't see any comments saying the US should just keep buying Russian engines.
