Google's stock-in-trade is personal data. They use it to sell, and they use it to gather more data and to make data about that data. It's kind of scary.

But Cloudflare's business model is different: they get rich by making the internet faster. Plus, it's great publicity for them. Their customer acquisition focuses largely on winning developers (by letting them use a great, barely cut-down-at-all service for free) so they use it in companies later. This helps with that a lot.
