There is plenty of discontent documented on the web, in blogs, on Etsy's forums (which are difficult to penetrate, since the search and navigation features are poor), on the forums of other marketplace sites, on Twitter, and so on.
They have a knack for turning away people who should be their biggest supporters. I can think of many successful shop owners have left after 2-3 years, disappointed by the way the site is administrated.
Yeah this is my experience with Etsy as well. I have a poor opinion of the company from talking to sellers who are friends.
I wrote a scraper of their site for friends to get their sales data for taxes. Years went by before they bothered to implement this trivial feature. My code worked because in two years their pages didn't change at all. Sorta crazy.
