Well, they're your fish. If you get enjoyment out of watching them eat feeders, then you should feed them feeders. However, as has been discussed, feeding feeders opens your fish up to a host of problems which wouldn't even exist in your tank if you didn't feed them at all. So, it's really a question of how easy you want fishkeeping to be, and how healthy you want your fish to be, and what you want to get out of keeping fish.
Personally, I do have one fish who refuses to eat feeders. I can tell you that wasting a 55 gallon tank in order to QT feeders for a month at a time isn't something I enjoy. However, he only has one eye, and so he doesn't act like the others, and obviously doesn't think like the others.
I think that, as time goes on, you'll begin to weigh the trouble of feeding feeders in general against the thrill you apparently experience when they eat them, and your fish will eat fewer and fewer feeders. Because it's really just a pain.
Also, ich usually comes from somewhere. Therefore, it was introduced to the tank somehow, likely through not QTing something -- this could have been the fish you actually keep, or the feeders. I understand that there was a catastrophe surrounding the outbreak of the ich, but I think it's important to understand the parasite and where it comes from.
The only truly safe feeders are feeders you breed yourself, such as guppies or other livebearers, like Mollies.
