Tailscale's actual scope WRT to data usage

After some more Googling I've found that Tailscale mainly routes
traffic between our own devices. This is why there's no data cap.

Now I see Tailscale as a limited version of what I do, which is use a
public VPS to route traffic from the Internet to my home machine
running my services as well as, my peers can talk to each other over
my Wireguard VPN.

I can also funnel 100% of my traffic outbound on a home device through
my VPS. The main limitation I have is my VPS provider's data cap which
with Oracle Cloud on the free tier is 10TB.

Now I see why people like Tailscale, for the limited use case of your
own devices talking to each other, one being a server running
something like NextCloud perhaps, it makes things easy.

I like and prefer my use of Wireguard + public VPS, but now I see why
there's interest in Tailscale for selfhosters who are hosting private
services only and no public services.

They have perhaps the best write-up of how Wireguard NAT traversal
works on their blog too. [https://tailscale.com/blog/how-nat-
