Extending the question:
In my mind Tailscale was primarily to expose local services but answers here sound a bit as if people used it as a VpN replacement.
If I do not want to expose local services but only protect me and hide from untrusted WiFi, would I better use a traditional VPN or Tailscale?
My thinking is that Tailscale could be the better VPN because they have a clean business model while pure VPN companies are all shady.
Tailscale can tunnel all your traffic through a chosen exit node so you browse the web and whatnot as if you were at home (or wherever the exit node is), so in this way it's a bit like a VPN from a VPN company, but it doesn't give you a list of countries to select from.
VPN companies aren't really in the business of selling VPNs. They sell proxies, especially proxies that let you appear to come from some country, and you typically connect to the proxy using the VPN functionality (particularly if you're using a consumer device instead of a laptop), but often you can use SOCKS5 instead.
Tailscale isn't in the business of selling proxies.
