I will expand, market data and surveys have consistently shown that the top three popular fetishes are .... rape/non-con, pregnancy, and bdsm. Meanwhile the bottom of the list is scat, and guro. Scat and guro fall into about 5% of the human population that are interested in it, however data has shown that over 60% find both those "tags" unappealing that if it is included they won't touch the product. That being said, it has also been proven that by being able to turn off said content the damage to appeal can be mitigated.
Now, trying to appeal to everyone is a waste of time... it tends to dilute content and lower the quality of content provided. In almost all cases, being able to turn off content that isn't the main focus increases the appeal of the product. So customization of a game is generally a good thing, however as stated prior... tags like scat and guro are highly unpopular... so unless that is the main "kink" of the product... there will be a loss of interest regardless of whether the content can be turned off or not... This isn't a baseless opinion... just what the market data and surveys I have seen show.
You don't have to like it, and it doesn't have to be about "money"... Its just data that can be kept in mind to know where the general interest will be and how one can expand that interest. The data supports my position on "build a bear" games. Though there is plenty of room to be had for a healthy non-butthurt debate.
