Google and every other tech company are desperate to justify a pay to play internet model because when people realize all this shit can be run cheaply and without ads they are toast. So ya, they will never promote mastodon or the fedverse
Constantly posting on other platforms about how you're not on Twitter or how Elon Musk is a bad person is several orders of magnitude worse than just using Twitter.
I hadn't really used it in years but I read some twitter accounts still so I had my account open to do that, but once that shithead Musk reinstated an account that tweeted child porn, I deleted all my old tweets that I could and deleted my account. I realize I'm just a blip to Twitter but it feels good to have it gone. I'm enjoying Firefish and Lemmy and Pixelfed.
I've seen the rebranded site written as "Xitter". Note that in the modern system for transliterating Chinese, the letter x makes the "sh" sound (e.g. the Chinese word for thank you is rendered "xie xie"). I think these two facts go together nicely.
