That point is flawed. It does not stop people from doing things like these.
The issue comes less from the open/closed source aspect and more of how confident the developer is in the models. I would also like to add that as opposed to modules, which can in one way or another be seen by at least someone even if ROBLOX Staff, there would be no real way of retrieving this source, unless with a decompiler, of which are somewhat rare now anyways, but the point is that with this approach, not only would someone be completely untraceable because the style is lost in the code, but it could case even more damage if just used in a script, as it seems “fine” or as if it were just any other open source script.
Yes, the code provided in the first sentence does perform the same function as the one in the screenshot. And it does so via a little thing I revamped/remade not so long ago.
If we’re going to try to keep our source safe then we’re going to move in to other things. Removing modules will if anything worsen the situation and cause people to use more cryptic things to make their code just that, theirs.
