Have you tried opting out? When my dad did, he ran into a mess of broken links and incorrect support pages. Eventually he got someone to opt him out over the phone... only to have the "xfinitywifi" network pop back up the next day. It took a few more tries to have it actually disabled once and for all.

I imagine the less technically-inclined would have given up a lot earlier in the process.

Actually, that did happen to me and I ended up just forgetting about it. At the time I also wondered if it was intentional.

In fact I've noticed conveniently broken web pages from multiple large corporations. I've ran into this issue when attempting to access privacy policies and other disclosures.

There certainly may be something nefarious about this. Comcast could certainly get away with it.
