ISTM that when eBay was isolated hobbyists and craftsfolk it worked OK.
When it became a mechanism for antique/used stuff resellers to find, buy, and then sell inventory as a business, plus an online flea market of new merchandise of dubious provenance, the whole thing got cutthroat for the participants. The eBay decided to squeeze both sides on fees and services.
It’s a trifecta of anonymous greed wrecking everything.
This next thread is not about eBay specifically, but eBay and auctions are commented upon by many posters many times. Some defending it; others dissing it.
