Well, that's resolved now.

An actual intelligent person called, and we talked.

They do not permit their signal to be shared via wire across property lines.

I made it clear to them that there WILL be wires between the properties, and
that future vandalism will be reported to the police, and that reparing
those lines will be expensive.

He also suggested wireless, and told me that they "don't have anywhere to
stand" on wireless sharing.  (!)

He is coming over to deliver the replacement cable, and to personally
apologize to my wife.

The technician will be dealt with internally, but they cannot give details,
due to privacy restrictions.  He seemed genuinely concerned over how things
were handled, and wondered why his guy didn't call him when he discovered
this wire, and ask for instructions.

So, it's negotiated to a win-win. I get to do wireless sharing (I'm talking
on it now!) and they get to enforce their no-wire rule at least as far as is
logically reasonable.

And I discovered the joys of DD-WRT, which I'd recommend to anyone who owns
a compatible router.  :)
