I think one of the things that come closest to this are european-style brands on Aliexpress (Blitzwolf comes to mind) that pretty certainly don't do any R&D but are building reputatíons for only putting their badge on products of decent quality.

Something I haven't yet seen provided without a very significant price increase is customer support (which could already mean just a page listing all products with specs or a community forum).
