Same for me, and as shitty as Comcast has been in other places, I’ve had only two non-power related outages with them in almost 7 years here. I think their service quality varies not only state by state, but even county to county in some places.

It’s a security\legal risk to allow adhoc wireless networks within your environment, pretty much any organization above a certain size has the same restrictions.

You could theoretically allow anyone to access your router directly, which would let them bypass agreeing to the Acceptable Use Policy, for example, shifting liability back to the organization for that users behavior.

Not true, you’re pumping their numbers up, which increases their valuation.
