I didn’t know NetBird existed. I may switch to it because it seems to be literally the same as NetMaker

NetMaker is like Tailscale. It uses Kernel wireguard unlike Tailslace which uses user space wireguard.

The only downside is that you need to pay for it or you can host your own server (but is kinda tricky to do)

Yeah that makes no sense lol. Who needs MAC addresses to debug and fix bugs? No one.

Changing the IP constantly is not going to prevent tracking on modern websites. They all use other methods to identify you like browser fingerprint and other ways to fingerprint you.

I don’t know why VPN providers promote themselves as like they are going to make your connection more private, everything is already encrypted (except DNS). You are just shifting the trust from your ISP to the people that run the VPN.

If you are in a country with a high rate of censorship or you just want to circumvent geo blocking, using a VPN is worth, otherwise, a VPN is just a way to change your IP address which, is not going to prevent any tracking.
