For a TV receiver an open cable is an open invitation to RF or Lightning "interference"... well some people would consider Lightning "interference".

Everything has a degree of religious dogma (aka BS). This one for cable.
The cable itself, shielded or not, can pick up radio waves. It's conductive metal, the end. Shielding thwarts, it does not prevent entirely.
- If the wire is headed, capping does nothing, it'd still leak in.
- If the wire isn't headed, why have it at all?
If lightning strikes, interference is the least of your worries.
Lots of cables company dweebs are indoctrinated with various crap, some of which was actually disproved as nonsense long ago. High-level techs tend to learn better over time, but the low-level techs tend to spout this sort of stuff.
Any ATI AIW card interference isn't going to be external unless you plug in a wire (essentially an antenna, even if not an antenna) into it. If not, then nothing to worry about. Any interference will be internal. If from the tuner, then it'll be the tuner itself. not external forces. The 9000s cards are the only ones to really worry about, and that's isolated anyway. A piece of plastic capping the port will do nothing.
Power is a bigger problem. I had problems in DFW, then TVA, and then some to settle here.
