Maybe, I guess I don’t know enough to answer that. I do know that being on a company VPN isn’t always a requirement, though.
Either way, I’m not trying to argue for one approach to ad blocking over another as a one-size-fits-all solution, I just wanted to point out that it’s possible to have more control over the network than the computer in some cases.
I tried it out for a little while and it was pretty good at remembering passwords that I had typed and printing them in plaintext later for unknown reasons.
