After reading the title, I thought "crap, I should probably know who Katy Perry is." After reading the comments, I don't think I'm going to bother looking them up.
This probably shouldn't surprise me. She was originally a Christian musician before she figured out that she was talented enough to make serious money if she marketed herself on sex appeal.
The most generous possible take is that it's basic politeness to thank someone when they give you a new truck (even if it’s a shitty one). My question, though, is why did he give it to her? Out of all the celebrities he could have given one of those stupid cybertrucks to, why did he choose Perry?
I don’t know much about her. Does she have a history of problematic behavior that would make Musk think she’s a potential ally?
That's only generous if politeness was ever warranted when it comes to Elon Musk. It isn't. Everyone should be rude to him at every opportunity because he has shown himself to be irredeemably atrocious bigot and conspiracy monger.
Squid, you get it. Musk is a thin-skinned hypocrite whose only actual contributions to society are vitriol and debunked ideas, and politeness is more than he deserves.
