Cool so, you linked to some git repositories that haven't been updated in 4-5 years, and looking at their current website there seems to be some sort of crypto involved now.

Minetest has been more a platform for making games on than a single game for at least a decade, since they added lua scripting. Seems like you're outraged over nothing with no real understanding of what Luanti has been and aims to be.
