I like snails, have since I was a little kid. They were my first pet, kept terrestrial snails in jars with leaves to eat.
The ramshorns in my tank hide so I don't see many and like to get into the sump. I have seen Corydoras eating them, have never seen them eat any living plants and they haven't ever had a population explosion.
The Malaysian Trumpet snails did have a population explosion then died completely off and I don't even have their shells left now. It was something to see and I understand how somebody who doesn't like snails could be horrified at the sight of heaving substrate and wood completely covered by pointy shells. They still didn't eat the plants, they were eating the excessive debris in the tank.
