There is actually a Chinese solution to this which you wouldn't prefer at all. Legally every place who provide free wifi will need you to do sms verification with your smartphone, and record your ip with your smartphone number (which in China is connected to your identity). Then they need not worry about liability, because if anything goes wrong, they can tell the police exactly who you are.
If you want both privacy and liability, it seems indeed only you can do is to be harsh on larger entities like cafe shops who provide free wifi.
Actually you cannot use your present Mullvad account to do so. Instead, Mullvad provided exclusive API for tailscale as partner account to do so, which you can only get from Tailsacle if you choose their service. Mullvad only allows those data to go through its server.
Given that Tailscale is a ridiculous company that advertises on privacy while force user to login via SSO by tech giants or OIDC which is shit in privacy, I will stick to my current origin Mullvad account and keep away from this service.
Can you name one authoritarian regime in which child safety has been a priority? If anything the impunity of those at the top has made child trafficking worse. Your position risks giving a massive amount of power to people who have already demonstrated they can't be trusted with it, let alone with kids. Don't assume privacy activists don't care about children.
> Second, The erosion of big tech companies' power is a benefit as far as I can see.
Big tech can't read E2E communications either. This won't reduce their power.
> Third, We still have effective encryption in our hands. TLS is not going to be broken by this.
Effective against whom? If it's the authorities you don't trust then TLS is already useless.
Seriously, the UK is the home of the coverup. Sir Cyril Smith, Sir Jimmy Saville, Sir Peter Morrison, Sir Peter Hayman, Stuart Hall OBE, Rolf Harris CBE. All of them connected enough to 'put in a call to someone' and in many cases, shown to have received some police or official support. Your system sucks but you trust these people enough to give them more power?
It is really fascinating that the first website I went to is exactly named "Why bkuhn's Website Looks Like Crap", where someone explains why he is sticking to Web 1.0.
