But... but... they're catholic priests, they not only have a vote of celibacy but they also consider it a sin to have sex outside marriage! Why would a catholic priest use a Dating App?

Religion is a joke...

As an atheist I think anyone, including catholic priests, straight, gay or otherwise, can love or have sex or whatever they want to do with whoever they want to (as long as it's a consenting adult of course), but I'd say for them it's a bit of a cognitive dissonance, as it's supposed to go against their core beliefs, they're not just catholic, they became priests...

I find the whole thing extremely hypocritical though, trying to uncover gay priests on the one hand, which is wrong because they have a right to privacy, and then the Catholic Church protected and just moved somewhere else to pedophile priests who abused children instead of bringing them to justice.
