Yes, but it can work in the opposite direction as well.
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.
Sure but for every person like you there's several people who are not knowledgable about VPNs and use NordVPN because it's the one thing they heard about the most.
And an absolute truckload of people deep in the para-social relationship who couldn't imagine their 'friend' steering them wrong on a product, intentionally or otherwise
Tom Scott is a good example of the influence of VPN money. He made an entire video about how and why he would not make ads for VPNs because VPN ads are deceptive, this video got millions of views ...and then later he started making ads for VPNs (NordVPN iirc). I always wonder how much they bought him for.
Pretty sure he made a video about him doing those ads when he did them to answer that question, but you kind of answer it in your description anyway. His objection to VPN ads wasn't the fact it was a VPN, but the deceptive content in the ads. Promises they don't deliver, benefits you get from basic SSL anyway etc.
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.
I believe the economics of VPN companies is that they have a quite inexpensive, commodity product which has a lot of churn. The ads get people to sign up for a month or two at any price, which pays for the cost of the ads.
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.
Nordvpn seemed like a decent choice for streaming bbc but I won’t use them because of a company advertises that hard it must be bad. I would never trust them for privacy they are too big
thr notdvpn ads may have enlarged the consumer market for vpns as well, which may benefit other vpns like mullvad (people that never heard about vpns are convinced by the ad that vpns are needed, searches more on google or reddit and end up selecting what is considered the "most private" one, that is, not nordvpn)
