Allthough not a pro but vpns are mostly mandatory for p2p filesharing as in most countries, downloading can be a problem, but sharing will screw you big time.
So, a vpn secures (ideall) all traffic from your pc to the vpn host. You then use the vpn hosts isp and so on (in a country where your government cant ask for your data ideally).
I‘m not sure how it works for https exactly. What if you download a file, especially.
Have a good one.
Also brainwashing. People get their ideas from other people. Some through books, some through those they call experts but we‘re very easily influenced. Getting blasted with biased shows and commercials that show us how „fair“ law enforcement is makes people easy targets for pushing dangerous laws.
