What if the banner language suggests they might break GDPR, but in reality they are not doing those things? If my SaaS forces you to select a checkbox that states you're agreeing to allow me to set fire to your house (which is illegal) - would the sign up itself be breaking the law? IANAL, but I don't think it would be; I wont be breaking any laws until I commit arson.

It's breaking the law because you're essentially being forced to consent to some thing that they legally must give you the option to opt out of. It's not about them doing it, it's about the validity of their request for consent.

If I hire a hitman to murder somebody, but the hitman chickens out, I'm still guilty of having hired a hitman, even if nobody died.
