There is a fundamental difference between Google and Cloudflare. Cloudflare has a real business that is based on paying customers. Google never had that. It was founded in 1998 and AdWords was introduced in 2000. Cloudflare is already 10 years old and not showing any sign that it will change its business model. As far as I am concerned, they are a trusted vendor and I will trust them with my business unless they change up.
