It being fiber optic seems completely irrelevant AFAIK.

Any ISP knows everything you download and you can be hit with criminal charges for torrenting, there's no way around it.

That's not true. As long as data is encrypted, your ISP doesn't know what you download. They only know the destination IP, but they can't read the actual payload. Same thing with torrenting - they can't see what the content of the torrent is. The way people get caught for piracy is by having their torrent client share data for others. So MPAA dudes basically fire up a torrent client, find some popular torrent for a movie they are interested in, and look at all the IPs that are part of the cloud and actively participating in sharing it. Then they send notices to the ISPs that own the IP, and the ISP knows which customer that IP belonged to at that moment, so they forward the notice to the customer.

But the ISP can't actually see the content that's flowing between you and the net, as long as it's encrypted. Making such man-in-the-middle snooping impossible is a major point for all modern encryption protocols. They know which websites you go to, but that's about it.

that's not true, it doesn't matter if the information is encrypted as an isp can assume anything because they know the exact address you got it from, as i downloaded one movie from a torrent site and i was immediately sent a notice from my isp that i could face 10 years in jail, mind you it was a very popular movie and from a popular poster.

You should never expect a large company to be upfront about random fees. Talk to people that do business with them and ask them.

They can assume whatever they want, the fact remains that they can't see the actual content of the traffic. Besides, how would they know that you downloaded this exact movie? Presumably the website you were on has more than just one movie available.
The ISP doesn't give a shit about what you actually download, they only care about how hard you are hitting their infrastructure. They send you notices that they themselves get from organizations like MPAA, they don't generate these notices themselves.

This wouldn't even be realistic for an ISP to do. They would have to maintain an up-to-date database of all copyrighted content and all the websites where you could possibly get that content from. This would be an enormous task, extremely expensive, and with no benefit at all to the ISP. At best they spend a shitload of money and get nothing. At worst they spend a shitload of money, you end up in jail, and they lose a customer.

99.99999% of the time fiber isn't run directly to the residence. Even in the case of Verizon Fios the fiber cable stops at the street and it goes from there to your house over a coax, and then inside the house it is all coax/cat5. Regardless, the physical means by which your internet is supplied to you whether it be over coax or fiber has nothing to do with torrent. Some ISP's have bandwidth caps that you agree to in advance. In more rural places your ISP may cap you at 20GB per month, but in a major city with the bigger ISP companies in the city you generally have no bandwidth cap; however they will sometimes bottleneck/slow your speed down if you are in excess of "X" data usage (whatever they determine that to be). If you are in excess of "X" data usage then you are generally referred to as a "Power User."

Not sure where you are getting this info from. Here, any time the ISP offers a "fiber" connection, the fiber goes all the way to your house and you get an ONT, not a coax modem.

He's right. Fiber to the home is still emerging. I don't know if 99.999 is accurate for America, but fiber to the home is still a minority. Typically you are copper wired to a neighborhood router and then that is connected to the isp with fiber. It just depends on how old your home is mostly I think.

Verizon FIOS is fiber to the home (ONT).
Dunno about any other cable company.
