As a result of which … the ongoing running costs of the service not being covered by such payments … either

1. the service is not good and the provider is running it through virtual servers on AWS/Azure/whatever, not real servers they own, located in different geographic locations — meaning, not only can their true location be easily tracked but your data is travelling through AWS/Azure/whatever as well as the service provider’s system.
2. the service provider will likely not survive long (all businesses’ new user uptake plateaus) and will, if it doesn’t simply fail, e sold on to some third party that does not necessarily have any interest in going out of its way to help customers from whom it will not receive any income and has, therefore, no motivation to guarantee the same terms and conditions they originally paid for,

There is no such thing as a free lunch on the Internet and you get what you pay for — if you want even the least semblance of a VPN being worth the money you pay for it … (few are and, unless you’re a journalist/activist living under an oppressive regime, it’s debatable whether any are in fact) … then you pay and you keep paying, because it’s a service, not a product.
