It's a game. The VPN marketplace is huge so it's wack-a-mole.

Big companies don't hide their VPN ASNs. Obscure, for sure, but getting a good list isn't hard. Usually they get blocked.

Smaller companies may pass under the radar, and have higher tolerance for risky strategies.

The fringe providers are the problem. They aggressively change IP ranges, front-vs-obscure ownership, and play dirty. Shady folks will resell residential ranges. End-users often get tainted goods.

... and you still have the collateral damage game when VPNs host infra with big cloud providers vs colofarms vs self-host, etc.
