This article seems a little misinformed: VPNs are still regularly used in business and are necessary for companies to function. That's still probably their primary use if I had to guess.
People who are trying to ban them clearly have no clue what they're doing as banning VPNs would be an absolute disaster, not just for privacy minded people or folks who want to watch something region locked, but for the basic tech functions of just about any sizeable business.
