If you pay for a newspaper subscription, you expect to get the news. If instead, tabloids showed up on your doorstep every morning, you would probably ask to have your subscription cancelled if that wasn't what you liked. The difference here is that there was a cost up front. It's like you go to the news stand and buy a TIME magazine, but when you get it home you realize that it's only the cover of a TIME magazine with BOP inside it. I dare you to tell me you wouldn't ask for a refund...
Except in this case the terms of the newspaper states that the "news" content can change/end at anytime. And you pay knowing that beforehand and or very shortly thereafter.
Also the newspaper gives a year's notice stating that they are going to change into a tabloid, and so you read the newspaper all the way up until that point. Basically getting your money's worth.
Then the newspaper says we're turning into a tabloid now, but you don't have to pay anything extra.
So you have the option of canceling or sticking with a tabloid.
In no alternate universe does the agent who purchased the newspaper expect a refund post facto...well except maybe this one.
The duration of use for me is a red flag.
You would have to show malice and deception on the part of SE to claim a refund at this point in the game and I just don't see it.
This may seem like a "grey" issue for some of you, but in reality it leans heavily towards the troll side of the spectrum.
In the end, for me, it's not about SE or this game. It's about this weird sense of entitlement (if the OP is not a troll) that people have. When there are FAR greater injustices and shady practices that are going on, than to be refunded $100 three years ago.
