The problem is that you don't understand how it works. Yes, you're ruining a lot of games, so it's normal for people to complain.
When a game that initially focuses on feet starts to include urine, then scat, vore, giantess, cuckhold, and many others get added.
In the end, the vast majority of players end up with 10 to 20% of foot fetish content in a game that was initially sold as focusing on that, with the rest taken up by each “niche” community that has its own little scene with each update. So yes, we're right to complain. Not to mention that even within the foot fetish community, there are different preferences that are incompatible, for example those who like stockings and those who like socks. When you take one of the scenes for yourself, they all end up being much more affected.
Develop games tailored to your preferences rather than sucking up to other people's games and complaining when that audience disapproves.
