I wouldn't say your devices are owned, but you should expect being monitored and your communications being recorded.
You could make an argument about the security of the modem of your devices, as that was often a target due to it not being particularly secure and it having wide access to your device, but I believe that started changing some years ago when this started being a more widely reported issue.
I wonder, do people from Paraguay "get" the accent from the different provinces? I mean it is pretty easy for us Argentines to differentiate a porteño from a cordobes and even someone from the northern provinces (specially if they use slang) with a short conversation
Granted, whenever I had any sort of conversation with someone from Paraguay I had trouble to differentiate their language from someone from the Argentine northeast unless they started using some Guarani words (and that is still not that useful given it is also spoken in the Corrientes province)
The problem is that I have to pay for another thing just to watch the thing I was already paying for.
Piracy almost always is caused by a lack of convenience, namely:
"I get the service, have a (sometimes very) limited selection of stuff, and have to pay for it, and if I want that other thing I have to pay for another entirely different service"
or
"I get anything I want with a little hassle, but for free"
