This really does not sound healthy. The game is released, for a certain amount of money. If people don’t like what they get for their money, they simply should not buy it.
But by now gamers have been so trained to expect to endless content treadmills and all their ilk like mtx and battle passes that publishers/developers get egged on if they don’t work on their game 24/7 and forever.
I don’t know, the bedrock version started in 2011 way before Microsoft bought the studio. It was never free or community-driven, it is cheaper than the Java version, but it doesn’t have access to the free modding community. This sounds like a relatively good non-toxic deal to me, either you pay upfront or you suffer the micro-transactions. If you don’t have the money, you can still play the full game for a relatively low price.
Your implication that they don’t optimize or develop new content for the base game is simply unfounded and proven wrong every year like clockwork.
