The fee increase literally only harms the sellers. I use Etsy at least about once a month - I'm a huge fan of custom knick-knacks such as this lovely 'fix your hearts or die' 'Twin Peaks' pin in support of transgender equality:

There's a lot of cosplay items, etc - Etsy is an incredibly unique market that looks like it needs a replacement with accountability towards it's community.
Sounds like maybe my next project, tbh. :)
