But I wouldn’t go as far as to say Mojang is lazy.
If not lazy, I'd call them maliciously incompetent. Any modder can put out all three mobs in an afternoon. There's a bit of a greater expectation for a multibillion dollar company making hundreds of millions of dollars every year.
It's literally drumming up as much engagement as possible for the least amount of work you can get. How could you not call that "lazy?" What else would you call it?
It wasn't even to release on their software platform, it was more explicitly a "non-Steam" release as games were available on PC via both Epic and Microsoft's Store.
