I remember that in earlier versions, there was a decency stat that increased as you made meals for your son.

Was that feature removed? There are still pieces of text that reference decency, but there is no longer a bar above corruption listing decency.

Did decency do anything?

If it is gone, maybe we could bring it back as a dominance/self-esteem meter of sorts. Like, you could get your boss fired or progress further with your relationships (such as with Anna and Marc) beyond just sex if your decency is high enough. And if decency is really low, you could start to see yourself as just an object to be used sexually and may even be unable to buy things like the chastity cage and condoms.

Also, here are the bugs I found:

In the new "art supplies" section of the shop, there is no back button, so you're forced to buy the art supplies if you have enough money, even if you already bought it.

Buying the smartphone and downloading OnlyFaps deletes your corruption bar for some reason.
