My nextdoor neighbor is a shoe salesman (in the US). He traditionally dealt with a region of retailers on behalf of his employer, a multi-brand company like VF, Clarks, Born, etc. In his previous role, he was asked to try to figure out how to add Amazon as a B2C channel. He did, and it essentially became his full time job. A couple of years ago he was laid off, and when his new employer (differently shoe company) learned he knew how to "use Amazon" he was immediately reassigned from field sales to full time online. According to him, there are so many quirky and esoteric things about selling through Amazon it's nearly impossible to figure out how to get started, much less understand nuances of pricing, taxes, shipping and returns, and -- as you said -- Amazon support is conflicting and inconsistent at best.
Nowadays, I'm fine buying consumables from Amazon if I need them asap, but for any name brand stuff I specifically want, I prefer purchasing elsewhere. If reviews were trustworthy, it'd be one thing, but with Amazon having turned into AliExpress, it's impossible to know whether any of the Chinese brands are actually trustworthy and of high quality.

IMO people buy cheap generic Chinese brands for the same reason they buy cheap dollar store products. They're gambling they can pay 30% the price for 90% of the function. Amazon reseller premium = they're paying slightly more for returns in case things break. They can save more buying from Ali resellers. Even more while temu subsidizing orders. The only people looking for quality are people who order from resalers of established PRC brands, i.e. Xiaomi. In the days before Amazon cracked down, you had brands like MPOW decide better marketting strategy was to give people gift cards for reviews and give no question asked replacements well outside of warranty period. Pretty win-win for consumers.
