Should you use leaks or not?

I don't think you should pay for garrys mod addons with the exception of anti-cheats and gamemodes cause a lot of work goes into those and don't get me wrong I'm sure a lot of work goes into the other things I just don't think that printers should cost like $5 or something like that I think its dumb and just a way to squeeze money out of gmod server owners that don't have the time or the knowledge to make there own add-ons.
