Freeleech is good for helping new and/or low ratio seeders recover ratio and get back into the mainline. I don't think making a torrent (mine or someone else's) freeleech has a net benefit to my seedpoints or upload count, but I have a lot of both, and sometimes I'll spend to points to freeleech an older torrent--mine or someone else's--to give it new life. There's some older stuff on here (10+ years) that will soon go to Torrent Heaven w/o being freeleeched that I think new users would find interesting.
Just my opinion, of course.
