I think a lot of people here, mostly in their own interest, ignore the fact that Roblox is above all else invested in being a safe place for children. Features that allow for blackbox code in games are inherently not safe for children.
Reguardless of if the developer is at fault or not, Roblox and their image is held accountable for anything bad that happens on their platform.
It risks situations that could be PR nightmares for Roblox as well as have serious other reprocussions if they were deemed “not trying hard enough” to prevent such issues. And worse yet issues could result in countless “good users” who trusted modules that they had no reason prior to distrust in a bad situation.
