We'll see if the trend holds in a month, a year, and a decade. I think the flaws holding it back will prevent any growth, charging money for mods is radioactive to the community as Railcraft had proven before they were forced by law not to paywall their updates.

Best case scenario we get the Google Play Store where people don't make stuff because they want to, but because they want to make money, but like I pointed out that MTX scheme is absolutely going to result in bad and confusing payouts which will drive away even those people. If it turns out they're paid in scrip- I mean minecoins, than at best you're getting a bunch of kids who don't understand labour exploitation yet.

EDIT: I looked into it and it's mostly just kids who don't understand how exploitative the whole thing is. The API is also extremely lacking.
