I certainly respect your different perspective, and I'd never try to convince someone "Hey, you should feel aggrieved about something you're currently happy about!
I totally agree with you that, if one wanted to ensure that Dominion online continues for many years, having an ongoing revenue stream makes this much more likely.
My opinion is informed by me buying the "lifetime" subscription at the old site just a (relatively) short while before the old site went out of business. If I had bought this subscription several years earlier, then I'd probably feel I got fair value for my money. But I didn't, so I don't...if that makes any sense.
Obviously, I feel like this site is a decent value, or I would not continue to give it my money. But Donald X got some percentage of my money at the old site, and he obviously had the ability (when negotiating his deal with Shuffle) to insist that "legacy" lifetime subscriptions be honored. He chose not to do this, and that was entirely within his rights. But a lot of us felt some resentment about this decision, and it is--of course--entirely within our rights to remind people of this. I got the free year, and that is certainly not nothing. But it was definitely not (IMO) a "fair" offer.
I strongly support your right to argue that I'm wrong to feel this way, or to point out other factors that I've overlooked or failed to mention. Having an open forum, where people are free to vigorously (but politely) disagree is a sign of health, and will not--I hope--be seen as a sign of weakness in our new Dominion home. I'm quite positive about how this site has implemented the game, and I'm pleased that they are making some efforts (albeit at a glacial pace, often) to address bugs or suggested changes).
I do not claim to speak for the majority of older players...I have no idea what each individual person is thinking or feeling, of course. But I doubt I am the only person who has some lingering resentment about how the move to the new site was handled. It's not a big deal for me. It's not even a small deal for me. But it's not "no problem at all" for me, either. :-)
