I can't understand why people would find it creepy. There's already a filter built into Tinder (show me women/men), why is an extra filter suddenly creepy? If a bot can know what I find unattractive and filter that out, why not?
I find that people will say things like "I prefer people with blue eyes", but what they are really saying is that the people they find attractive often have blue eyes.
Humans don't seem to be able to actually determine the characteristics of a person's looks that makes them attractive, and rather resort to pattern recognition bias. So instead a computer is able to determine what you are actually attracted to as it doesn't have the same bias and is able to consciously distinguish more data from a person's face than the extremely basic set a human can.
