No, the government is requesting something to be taken down. Short of the exceptions mentioned up above, the platforms are not obligated whatsoever to follow those requests.
My understanding is that there is already court precedent that the government can’t do this (use private companies to do their censorship even if it’s not strictly guaranteed to happen).
There is, even if the companies can refuse. The government cannot ask companies to censor something. This is a direct violation of the first amendment.
I would be pretty surprised if this was true but 3rd Party Doctrine is in good standing in 99% of cases.
Edit: Yeah, it appears this is not true at all. The government of course cannot coerce a private company to do this (which is obvious since that'd be tantamount to the government itself doing the censorship), but they absolutely can request it. https://reason.com/volokh/2021/07/19/when-government-urges-p...
