Honestly, fuck on-line platforms and their arbitrary bans. In meatspace, you can't be just banned from a store, or a store chain, not without a criminal record at least. Sure, user accounts are governed by vendors' ToS, and any store can ban you from their loyalty card program for any reason, but off-line, those are all incidentals not required for completing a purchase. On-line, identity, security, and optional marketing crap got bundled together into a single "account". It's a historical accident that needs to get corrected, possibly by regulatory means, to harmonize it with the general expectation that the store can't refuse you service for extra-legal reasons.

I have bought from amazon exactly once in four years now, because a vendor (a chinese one!) has Amazon as the only outlet where they provide warranty because they are plagued with counterfeits and bootleggers.

I find that fact for a chinese reseller so incredibly ironic. These guys are good people tho, bunch of gamers making the pinnacle of controllers for pc gaming with mouse clicker buttons and whatnot.
