Is there much Markey can do here, especially given the composition of the House in the next Congress? I'm also not sure there's much Markey can do to regulate a privately owned website, and I'm not sure the government should even have that degree of power.
I think #Congress and other government agencies should start up their own #Mastodon or other #ActivityPub based servers if they are serious about addressing this issue, as that would actually help address it. Complaining to Musk (who won't listen anyway) and grandstanding about doing things they cannot and should not do, on the other hand, does nothing.
