It is also correct. Every European company using FB/IG are acting illegally. It is only illegal if you get caught. So, just like speeding or overloading your truck using FB gives you an advantage until you are caught.

True,it will probably have an economic impact. Still, there are several ad options/platforms still available (Google, Tiktok,...) so one would hope that a sizeable amount of the businesses would be able to move their ad campaigns to those instead.

This reminds me of employees who think their employer will collapse when they leave. It's rarely true.

The world would be fine without Facebook, other people will step in to fill the void.
