I have no issues with monetized mods via steam so long as meets the following 2 criteria:
1) The maker of the game is ok with it being sold.
2) Selling it for money is the choice of the modder(s) who created it.
I do, however, have a huge issue with the way they are doing it. 75% of the profits is crazy. And I believe they will only pay out after it's made something like $400 or whatever. Meaning that niche mods sold here will lose out on 100% of the profits.
The backlash on the way this is done is absolutely warranted, but will see if anything comes of it.
