I forgot the name but 10 years ago there was a popular free vpn extension for browsers that let each user exit by the other users ip and you could choose the location with a click.

But behind that free service, the model was to provide an expensive service to companies needing high frequency testing or scraping (sometime illegal) with multiple ips and locations. I got a trial for 1 week after a visio with them, it was complicated to setup, but it felt like exploiting unknowing free users.
