This site feels like this it's made by people that misunderstand games and genres and can't stand the concept of live service games which surprise takes money to run.

Saw one where powercreep is considered unhealthy ...if you played a competitive card game without power creep you'd quit because the first meta would be the only meta. Controlled power creep is healthy for game longevity.

Some games have enough room for new meta to develop even though there have been no updates.

That doesn't mean that's the only way to be a good game, and I don't necessarily have an issue with powercreep. If it's mild and expected, powercreep can also be a way to handicap... If you're introducing new people to a game, maybe you let them use current cards and you use 5 year old cards (or whatever), they get to practice with current cards, get to experience old cards, you get some nostalgia from your old decks, and you don't have to sandbag, because they've got an advantage.

I would not consider SaaS healthy. When it comes to games it is straight up drug dealing.

I think what they would want to see is the cards all be free. That way powercreep does not make a purchase less valuable, does not make people gamble for cards they want, and not give an advantage to people who want to spend more money to get good cards.
