Which law?

I ask, because many times people point to the first amendment for things like this, but that doesn’t apply here.

What exactly do you mean by “protected speech”?

The reason this needs to be illegal is because jamming the signal is not specific to you. You block your signal but you probably will also be blocking it for anyone else in the vicinity. Plus the way these things work they can create interference for other types of signals as well. It isn’t the blocking itself that’s illegal, but the interference that you’re causing.

Try pivpn. It is meant to run on a raspberry pi, but it should work on most Ubuntu and Debian based distributions.

In legal proceedings, statements like this are allegations. They are not considered to be true or factual until proven in court. You’ll see the word allegedly used even if it seems very obvious that someone did something because that is the correct way to report it.

There are places that have on demand busses rather than fixed routes.
