Personally I don't have a problem with fragging frags. I don't have a problem with someone wishing to recoup some costs because the frag cost more than they wanted to spend on it. It is their business and I either decide to buy it or not (usually not...but doesn't mean I hate them for it).
Ultimately it helps spread out the morphs and eventually drives down the price so that it gets to the point where I feel it is worth it for me to purchase it. There have been numerous morphs that have gone from hot collector pieces fetching top prices to essentially common place in a period of a few years.
Maybe as an aside topic....next weeks or part of this discussion; which is a bigger travesty?... Fragging frags or having one person buy the only known colony of a morph and never fragging it?
