i will say they are right about one thing, small sellers are getting totally run over by design theft and aliexpress resellers. as a buyer, its a huge pain to have to sift through pages of aliexpress merchandise to uncover interesting and original work. make a cool printed design on a game boy shell? quickly stolen, mass produced on aliexpress, then sold by all the boring resellers on etsy. 90% of rpg dice sellers are selling the exact same stuff they got from the exact same bulk deal.
one of the biggest problems for me is im never even sure if im buying the original design or a knockoff, which totally sucks.
idk if this is just affecting the retro games / dice communities, or if others are also hit. ALSO you can kinda just sell semi-illegal "grey" goods on etsy? TONS of sellers just selling bootleg game boy games and rarely mentioning that in the product description.
