It doesn't actually allow them to do anything they couldn't legally do before, but it makes the penalties a lot stiffer to discourage large companies from breaking the law.

The problem before was that even if you had a contract, the company would basically say "we have a lot more to spend on lawyers than you, good luck".

Now they have changed that calculation with this law, where if the big company loses it's a huge cost to them. So now their calculation is that it is cheaper to pay their bill than to fight you in court.
