> Ms Kendall told Nick Ferrari: “I told MPs yesterday I'm going to come back to the House with a statement on the issue of VPNs in July. There are very strong views on both sides of this. For some people, it is about privacy, and it is the ability to use that is really held strongly by people. And for others, they say they should be banned because kids are using them to get around. And so I— the main thing that we've done is we've commissioned additional research on this because I've not been happy with the evidence."
Sounds like they realize there are two sides and no "clear winning argument" in either direction, that's why the additional research is needed. Sounds a bit more nuanced than what I expected based on your snippet.
"I want to do the thing that gets me the most votes and carries the least political risk". Note this is not necessarily the wisest thing, or even the thing that objectively solves or mitigates the problem the most. Many such cases...
These people created a law that is catastrophic for privacy, so I don't believe they will be stopped from banning VPN's just because someone claims VPN's are good for privacy.
>both sides
What is there to research? Yes, VPNs can be used to circumvent geofences (and by extension, regional age restrictions). Yes, attempting to age-restrict VPNs is at odds with strong privacy guarantees. Privacy is a human right, and one which is essential for effective democracy.
