Not to be that guy, but do you have a source for this? As scummy as what they're doing is, it's also completely typical for damned near 100% of companies to reserve the right to be scummy. They all have a clause in their terms that states, 'We can do whatever we want, whenever we want, for any reason we want. If you don't like it, your only recourse is to stop using the software.'

I'd love for this to be true, but I've never seen as exclusion or other sort of work-around for EU customers in any sort of terms for this exact condition, so I'd be extremely surprised to find out it's really not allowed in the EU.
