It seems, however, that at least some VPN providers use their customers' bandwidth without their knowledge to route other customers through it. I'd say that qualifies as sketchy.
Although on an entirely personal level, I'm not a fan of stuff like going through VPN to use Disney+. I think people should ideally either not watch or pirate geoblocked content. Consuming geoblocked content through VPNs is basically letting such companies get away with discrimination and still get your money.
The internet made them largely redundant, but they still had their contracts and pushed to have things like geo-blocking to maintain their "local monopoly" arrangement.
When legal options are not readily available to me due to geo-blocking, I have no qualms about pirating instead.
Just because this type of licensing contract is common in the media industry doesn't make it acceptable. People should just pirate whenever they hit a wall like that.
I pay a significant amount of money for MLB streaming, only to have many games blacked out. Due to various factors, I cannot legally get access to those games.
