And that's the big unless.

You may be right for small point releases but when they revise the interface or introduce significant new features or something else which people will notice and want, it's going to put you at a disadvantage.

And because you don't have access to the new version you don't know whether it's going to be a significant release or not. You may be competitive, you may not, you simply don't know.

I honestly don't see how that doesn't put a company at a disadvantage - it's certainly not a level playing field and it's certainly not a situation I'd happily put myself in.
