Do you also disagree with the causes he is promoting or only the person and/or methods?

Some of his ideas, like full anarcho capitalism, I would need to be convinced before being onboard with. But opposing mass surveillance and promoting government accountability seems odd to vigorously oppose.

He describe himself as an anarcho capitalist so I guess, ideologically, it is government surveillance that he is concerned with and that the free market will sort out the rest.

I think they mean secret as in unlisted where their records aren't accessible in public government databases. The same protection you would get if you were stalked for example.

It would be interesting if you could elaborate on the claims that be was a corrupt police officer and drug dealer.

My understanding of his own account is that he left the force when he wasn't comfortable arresting people over weed and that he saw systematic abuse of power that he didn't want to partake in. Is there more to the story?

His recent activism has been focusing on contrasting the privacy people in power demand with their work to deny the broad population privacy.

It works well for capturing serial logs, a console or software updates in development. The advantage i saw was that I could order 50 cables from a distributor and give one to everyone that works on the device.

If someone needs one on the other side of the world, they can get one from a local suppliers.

Hot plugging hasn't been a problem in my designs, I add a series resistors to the uart net and ESD protection if software developers will use it.

When I use it for other devices, like routers, SBCs and IP cameras I avoid hot plugging and leaving it connected when the device isn't powered.
