There isn't a constant backlash from the public - most people don't care, the ones that like it buy and the ones that don't write grumpy blog posts about it. The people who do care have split into the aye and nay camps and are arguing the situation out. The usual anti-capitalist types will hate it, but they hate everything financial.
