When a VPN was happy to work with him on an ad that wasn't deceptive or misleading he was happy to run it. I think the original video only existed in the first place because at that time he was willing to advertise a VPN for the money offered, but they couldn't agree on ad content he felt was fair. So his price never changed, the VPN company just gave into his 'advertise honestly' demand.
Tom Scott’s video a few years ago helped, but some creators still seem to be saying or implying that using a VPN makes your browsing “safer,” which unless you have a very specific need for a certain kind of safety, is untrue. I wish VPN companies would audit the claims their partners are making about them, but there really isn’t an incentive to do so —- if their brand gets damaged irreparably they can release a new VPN under a different brand.
If basically every NordVPN ad on YouTube is talking about safety, you can be fairly confident that it was a talking point provided by NordVPN.
Eg, all the Youtube ads of NordVPN only did was to convince me that if I'm ever in the market, I'll use someone else. Part because all that advertising has to cost a lot of money, which of course the subscription has to pay for. Part because some of their advertising is less than completely honest about what they provide.
