Musk has stuck his neck out so far on this. He's a world famous billionaire, he's one of the strongest personalities on Twitter, he's know all over the world and possibly space and he says there's no room for remote work in his business. This is the opportunity everyone here has waited for!
If the workers of Tesla refuse to go to the office the entire world will notice, he WILL tweet about this and try to blame whoever but the fact is when, not if, he announces to the world that HIS workers will not be swayed we'll have finally made a point.
