I agree that is what it would take to get a high score on their site but I think it's an unrealistic expectation to suggest that the developer should be on the hook indefinitely for content. Each card game set is functionally a new game with some costs amortized thanks to it's previous sets.
We have seen the forever sticker price in mega hit indies ala Stardew Valley or Terraria but I don't think that is really healthy to expect for gaming as a whole and is more that small teams hit a home run.
Why should developers be on the hook indefinitely for content? Why can’t they just make a good game and sell it? If a game needs continuous ‘content updates’ to remain good, it simply wasn’t meant to be played forever. Not all games are.
Your argument seems to be “won’t someone please think of the poor defenseless billion-dollar international megacorporations?”.
