What do addon devs think?

They may feel bad, but let's think that their addon is so good that people want to leak :D

I think devs will feel really pissed off it's a majorly big addon that they've spent such long periods of time working on, But if it's something that took them like tops 1 hour to make, I doubt they would be that bothered in my opinion.

In my opinion, the creators certainly annoy the fact that paid addons are increasingly available for free, but generally I do not like the addons are paid. But if he needs a paid one, I will buy it.

Well personally the feeling of people free-loading of my work is initially frustrating, but as long as I have passed the break-even point the rest is bonus as far as I'm concerned.
GMod is meant to be a community where everything is shared, so with this understanding I can't really get angry.

Developers will usually go after the leaker and ban them from gmodstore, thats what happend to other people
