It's not Group Think I would say, more capitalism. SpaceX has all the big name banks and VCs and investors involved.

So the banks know that if they don't fall in line, the VC's may not select them for future IPOs/make them lead bank and also not use them for other work. And the banks know that the big name investors who invested in the VCs are also their high net worth day to day clients buying their services.

The banks loyalties and financial interests are not in protecting normal everyday people, it's protecting their business and individual bonuses. (SpaceX paid around $600 Million in fees for the IPO! And that's after negotiating a low percentage).

The news sites know that if they speak out of line too boldly, they won't be 1st in line to get exclusive stories and invites to events. Or Advertising Spend.

It's for governments and regulators to put rules in, otherwise capitalists will carry on in their own interests.
