Cable TV systems have always had problems with RF leaking from and into their "closed systems."
This is a bit one sided industry view that is nonetheless interesting.

At one point the local cable system used a pilot tone smack dab in the middle of the 2M ham band to set the automatic gain of their 'gazillion' line amplifiers. Their system leaked like a sieve and a group of local hams sat up an impromptu network on that frequency, which shut the entire cable TV system down.
?
The cable system was violating the law with excessive leakage. The same technical flaws that result in leakage that allow radiation of cable TV signals also allows external RF to get in.
?
The cable system issued vague veiled legal threats, which resulted in the FCC paying them a visit with an order "Clean up your act, now."
?
The spent a not so small fortune upgrading their system. it took them less than a month. The engineers I worked with (and me) were offered nearly obscene amounts of money to pitch in. They needed more warm bodies with technical skill than exist in

Was it a mean nasty act on the part of hams? The answer depends on which side of the fence you are on.

Similarly, in the early 1980s the Grateful Dead played a concert in Lexington, their roadies made the mistake of using 70cm ham radio transceivers, which really upset the local ham radio community. Which lead to another impromptu net on the roadie frequency. They tried to change frequencies but the hams followed. The roadies finally gave up and did the setup the old fashioned way.
?
The take away here is hams are tenacious bulldogs with rabies and an attitude when it comes to guarding/protecting their frequencies.
