First of all Hetzner would't let your server to be DDOSed for 192TB if it's not your normal usage. They'll likely just null route your IP if serious attack hit.
They also likely drop any charges if you escalate via support in case it was actually DDOS. E.g if you normally have 100GB / month and now you magically have 50TB / day.

What Netlify does is a scam.
