Unfortunately he deleted the tweet and I can't find it anywhere, but it was mentioned during the whole "Twitter Files Brazil" saga where Musk explicitly said "Starlink userd won't be affected if X gets blocked".
Musk is well known to tweet inflammatory, controversial, or fake stuff and delete the tweet after few days.
I personally observe some of his viral tweet to be deleted later multiple times.
At some point I had a burst of motivation to start writing a bot to keep track of all the stuff he deleted for people like you to observe, but was quickly disgusted to waste any time to be on top of the argument with some stranger.
So yeah, without google or other search engine's ability to index the whole twitter, everything is written there is hearsay I guess.
