In a lot of jurisdictions a contract that you were not able to negotiate properly is simply void.

Sure, a ToS is different, and there's basically an implicit contract when you buy a service, but that doesn't mean that the ToS is all powerful. It can be still unfair practice. (Some jurisdictions have that too.)

Now of course courts can't really force G to do business with you, but as others mentioned they can be sued for damages.

Still, you have to read TOS first to understand which part is definitely enforceable and which part isn’t. Ignoring it completely is foolish for a business.

In my jurisdiction it is assumed people do not read the ToS and any part of the ToS that is not generic boilerplate must be shown separately or otherwise highlighted, otherwise it might as well be food for the shredder.

That plus business can certainly not terminate your business relationship for any reason they like.
