Centralization is bad for everyone everywhere.
That bring said… I just moved my homeserver to another city… and I plugged in the power, then I plugged in the ethernet, and that was the whole shebang.
Tunnels made it very easy. No port forwarding no dns configuration no firewall fiddling no nothing.
Why do they have to make it so so easy…
Once configured, Tor Hidden Services also just work (you may need to use some fresh bridges in certain countries if ISPs block Tor there though). You don’t have to trust any specific third party in this case.
Wouldn’t that be slow?
Yes. Very slow. And only accessible from tor clients or tor2web/onion.to-like constructions. Which adds additional delay and errors.
There are things for which onion addresses are the right solution. This is not one of them.
It would. But it’s a good option when you have computationally heavy tasks and communication is relatively light.
