Cloudflare might get some benefit in the ability to track end-users across more websites as part of their efforts to determine who is a real human versus a potentially-malicious bot
It lets them get a very wide base to test products against, which in and of itself, is a huge benefit. They can test out far more edge-cases than anyone else in the industry at the moment.

Actually, they've said that their free tier is what gives them a paid tier to sell to other people. They know most people aren't going to buy anything from them, but the are fine with that because they get to collect a ton of data about who is using hundreds of thousands of websites in order to figure out what traffic is bad. Without that huge user base, they can't do what they do.
