It initially started as Minetest clone but it hasn’t tried to be one for many years. There are mods that try but not all of them do. There are a lot of mods and games for it on contentdb.
The video doesn’t say that Minetest is a Minecraft clone. The title doesn’t say that either. You can prefer chess to checkers without checkers being a chess clone.
Also with that same logic you could say Minecraft is just a Infiniminer clone. For that matter you could argue that any voxel based game is a Infiniminer clone. Think Veloren, cube world, Roblox and the like.
Edit:
I also forgot to mention that Minetest predates Minecraft (Minecraft is from 2011 and Minetest is from 2010)
Minecraft has become the defacto standard to compare to because it is the most popular. Infiniminer only has voxel building, but Minecraft isn’t a clone of it because it became more popular, and took the idea MUCH further. It refined it, and made it better.
Minetest is a cheap half-assed recreation of that. If their idea is to be Minecraft – but extensible via API/LUA programming, they have a long way to go. There’s a 30 min tutorial for Godot that would put you about where Minetest sits right now in terms of quality.
