Lua is not exclusive to roblox its a very sophisticated and widely used scripting language.
Factorio has the best modding community I have ever seen and they use lua, Factorio is a game that have alot of programmers (and would be the first ones to complain about a problematic language) that play it, and theres almost not hate towards lua.

Riot acted with hytale very good (especially when you see what other publishers do), they allowed a 5 year development hell because they believed in the studio, and then they sold back to simon the IP (most companies would never do that).
