It is my understanding that ISPs have management software that watches all the ONT activities. They will mark a rogue ONT as an “alien” and blacklist it.
not to mention that its probably jail time in the USA if they want to go after you. All they have to do is to show a judge that you "hacked" their device with some hacker "jtags" to extract the very well protected passwords.
People have in fact done prison time for "uncapping" DOCSIS CPE (although I believe only in situations where they were making a commercial operation out of it). I love seeing sites like this, but if I were involved, I'd tread lightly around commercialization, advertising, taking donations, etc.
