I don't see a CDN as something that customers get bored of in the same way as coupons for random services.
When a consumer realizes they are getting 50% off of a service or product they didn't want or need in the first place, they stop signing up for deals. Also, once the businesses realize these customers don't provide repeat business and they are devaluing their product for consumers who do want it, they stop offering the discounts. Finally, it's trivial to sign up for each of their competitors and play them off of each other.
When does a Cloudflare customer stop needing secure, performant content delivery, and how easy is it to switch to a competitor?
