This is a great question, and I don't know if the answer is as clear cut as the "No" responses here suggest. With 1TB free, Cloudfront has now removed the incentive for AWS customers (those who use EC2 or S3) to adopt Cloudflare's free or even $20 tier. While Cloudflare doesn't make much money off these customers, it's how their network learned and grew. 1TB is more than enough for a lot of applications.
