I've used NordVPN for a couple of years and never had reason to switch. None of it gets in my way, and it's just worked.
I'm sure others are just the same, but ive no reason to put in effort to change when I have a working solution.
Plus it's double effort cus I dont think anyone else does a meshnet alternative so I'd be setting up tailscale too.
If you're referring to their announcement last year about discontinuing meshnet, they've retracted that.
I know there are alternatives but why would I go to any effort to set them up when i have something that has worked exactly as I want it to for the last 2yrs? The cost of nordvpn is sufficiently low enough that I wouldn't switch to something just because it's free.
