I don't mind the honest ebay sellers at all. It's of course more desirable to swap figs for some of us, but that has its downside too. Some people are simply more assertive than others about asking. Also, being in the right place at the right time helps. And sometimes the desired varieties just arent available unless you are willing to spend some $$. If you want something bad enough, and if the money goes to a private party on ebay, good for them. No one has to bid. :)
In addition, for people just starting and new to the boards, buying is often the only option. People are discouraged from immediately asking for cuttings when they join since that is considered rude. And if you are careful about the sellers, ebay is as good as any place to buy. In fact, it's the only place some of the less common cultivars can be found. And then the price goes up if several people want the same thing. Supply and demand.
In the end, I don't think it matters all that much. There are enough figs and cuttings and buyers and sellers and swappers and commerical nurseries that everyone should be able to find venues they are happy with.
Thus far I've purchased rooted figs from a nursery, bought cuttings from internet sources including ebay, acquired local cuttings, and been the recipient of cuttings from generous board members. It's all good. :)
