I'm not sure I get why "sky tweet" is a stupid name. "Tweet" was a pretty arbitrarily chosen name for a post on Twitter, but now that "tweet" is a pretty established word, it seems reasonable to use a portmanteau based on that word for a platform based on that platform.
Though in practice I think "skeet" was a bit of a fad to be provocative, and most people just call them tweets, even on bluesky.
