"If the telemetry is of concern"
There's an implication that it isn't of concern to you.
Have you read and understood the T&Cs? Go back and read them again.
Read the bit that says they keep your login credentials. Can you find anything that limits it to login credentials to their services? The bit that days they won't keep login credentials for your bank or your work if they feel like it? If you can't find that doesn't it worry you, even just a little?
The same thing about keeping details of your transaction - can you find anything there that restricts them to just purchases from MS & not M&S?
Or did you think that this was just an oversight & MS couldn't find a lawyer to check them over?
