Seems like it’s completely subjective, too. I’ve seen many posts on reddit about people being shafted by the IRS and forced to pay back a ton in taxes even though it was a legit effort to run an actual business, simply because they don’t “think” it’s a business

This is only for new members.

Incorrect. You should reread what you included.

as long as your subscription remains active, we will continue to honour the same price you’re paying now as part of our “Grandfather Rate”

So you’re locked in basically to that rate until you cancel. It’s not for new members specifically. But there’s not always going to be content that you enjoy playing. People who stay subscribed to an MMO forever are people who have tons of money to just throw away. I play World of Warcraft, and I have never just subscribed for a year at a time. Sometimes I get busy and I don’t have time to play, or there’s nothing I enjoy in the current patch.
