A few years ago, I had an employer come up with the idea of a web application firewall that involved routing all of the customer's traffic through our network. I don't think I've ever been as horrified to be in Ops as I was that day. Thankfully it never came to pass; the architecture was changed. The idea of being in a role where all we could do is make the end user experience worse was fairly terrifying. (Leaving aside the possible benefits of caching of cloudflare-style caching, of course).
