I guess in your world everything is 100% litteral? You don't call it a bully tactic because your feelings get hurt...........
Of course it's the users choice, if MS tells you, "we don't support this software anymore", you can't turn around and expect them to help you out with your problems regarding the software, however, it's your choice to still use this software, and them actively going in and telling you, we can't block you from installing it, but what we will do is make sure that you can't get the updates currently available, why? Because we'd rather you pay us for our most ad-filled Windows yet, and no other reason.
I don't know where you read this as me saying something similar to "the customer is always right", again it's not one of those things you take literally, it's meant as to say that since it's the customer who pays he/she's the one you listen to when it comes to asking them to pay, unfortunately for all of us, MS is a monopoly pretty much, so they can completely ignore this rule, as we see, especially when there's apologists who lets them get away with everything.
