Sure, the whole ML community has to get together and hold a council meeting to debate this issue and then write a formal letter to hardmaru which tells him to stop liking Musk's tweets or else!!

Not sure, if you have understood it, but you can like whatever you want. You can also follow whoever you want. If you don't like hardmaru, because he flushes Musk tweets down your timeline, then just silence or unfollow him. It's your right not to like or follow a certain person, it's not another person's obligation to be liked by you.
