With respect, players are free to customize their own game as they wish (obviously, insofar as no laws are broken and no one is harmed). I've merely given players the
option to change something, if they so desire, and it seems quite... demanding to try and outright ban them from even having the option. They are free to do as they wish with their own game, be it replaced all the sounds with loud farts, turn everything pink, or replace all the avatars with cartoon ducks. Yes, even if it goes against your creative vision and you detest the color pink.
Additionally I should point out this mod contains absolutely no code, images, or any other assets taken from your mods. Just as you can add to or modify elements of the Starsector game without getting the developer's permission, so to are others allowed to modify your work as long as they aren't re-uploading any assets from the mods themselves.
I mean to be truthful here, *none* of those mods made any of those portraits so they are all, to say it nicely... "Borrowed". Which is one of several reasons I am asking you to not add them to THI.
While the portraits themselves come from other sources, it should go without saying that other portrait packs have remained on the site for years and years without being removed, so I think that sets a precedent that it's something acceptable. I suspect that if any of them were in violation of any rules, they would have been scrubbed away long ago rather than remain up. (Along with nearly every user's forum avatars as well, I suspect!)
