This is why I have an ongoing case against a UK based content streaming service who have just moved the goalposts and cancelled/withdrawn my ability to play back £70 of paid for content on the device I bought it on. They are arguing that the T&C's allow them to withdraw device support at any time, which I am contesting under law as this statement is actually hidden away on page 7 of their T&Cs and not displayed prominently at the time of purchase.
