[uncomplexity_]

why, what's wrong with it?

on the minecraft tips app, you are paying money for something that saves you time.

on this one, you are paying for the same thing here, unless you wanna reimplement it by your own.

and there are lots of avenues to have an edge, such as support for other framework / libraries, better / more efficient implementation, more configurability / control on possible variants.

please don't shoot down people on their attempts to make a living on their efforts.

Exactly. Some people feel entitled to get everything for free. It's obvious a lot of effort went into building these. If someone does not see the value, no one forces him to pay.
