> The new name isn't great (too many vowels in the same place, you couldn't spell it if you heard it)

That's only a problem for english. Finnish people (and I can say romance language speakers) would disagree.

I am an English speaker and disagree too. The spelling is fairly natural to me (probably how I would spell it if I heard it) and, in any case, English spelling is not exactly known for being obvious.

The new name lacks context that the old one had. Imagine discussing it on a bad telephone connection:

“There’s this game similar to Minecraft; it’s called Minetest. You know like, mining and testing”

Vs

“There’s this game similar to Minecraft; it’s called Luanti — uhhh, l-u-a-n-t-i”

The new name isn’t hard, but it’s definitely not as easy.
