ISPs will do the most boneheaded things to your traffic if it is not encrypted. There was a time when Comcast liked injecting random HTML into pages. I'm sure this guy has never had to "diagnose problems" resulting from an ISP rewriting HTML on the fly. Nowadays with TLS, ISPs are mostly out of the picture and the surface area for problems is dramatically smaller.
