yeah I started letting domains expire last year, this year I already let go a couple. it's insane what used to cost $5 is now costing $30 for absolutely no reason other than greed, don't tell me it's inflation because this has absolutely no extra cost for the registrars.
It's a fucked up model and I simply stopped playing. I'm trying to reduce my domains to only a handful that I really use and will not "buy" anymore. a rent model without an option to buy is really a time bomb waiting to blow in everyone's faces.
