I have no problem with this except that I won't spend any money on third party mods. I love PC gaming mainly due to the ability to have access to modding content and tools but I am unwilling to pay for it.
Call me cheap or whatever but I just won't. Of course I'm not going to fault Valve or any other company for enabling paid mods nor would I fault a modder for charging for their works. Just count me out on the usage of mods unless they are free.
