Google has SO much money, they could probably afford to curate the web and white-list websites one at a time and still make money. Personally, I think Google should get out of the search-indexing market entirely and rely on website submissions only.

At this point, it's no different than an appstore in terms of volume. Ironically that's where we're heading with most websites being "3.0" and just SPAs and now PWAs even.
