Generally, the agreements you agreed to allow them to do this.
Those agreements tend to be held valid (despite what folks want to happen ;p)
If someone you bought it from made implied warranties around this, you may be able to sue them (They often cannot disclaim implied warranties in consumer transactions)
Today I don't have time and I think it might one day be a good thing to be able to say: "you seriously thought anyone read and agreed to that thing? bwa bwa bwa hahahaha".
I think this part of law is ripe for some serious updates; some updates that will hurt a few established law firms but help everybody else, users, companies and lawyers currently boring them selves almost to death over standard contracts.
I'd hope in the future we'll have baseline contracts (around here this is already partially implemented in a few areas) protecting both users and producer, but seeing UK trying to implement restrictions on photography I'm not to optimistic.
