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...
