Earlier quoted context omitted.
That Apple documents that 'normal' VPNs are broken on iOS doesn't change the fact that they're broken.
VPNs were always meant to carry internal traffic to a private network, not the public internet (hence the name Virtual Private Network). The fact that a VPN server can send you a route for 0.0.0.0/0 always was and always will be a happy accident.
This. And the idea that these so called ‘VPN’ services somehow improve your security and privacy on the internet is laughable. All they do is let you get onto the public, untrusted, internet through a different on-ramp. There is no point to them. The internet is just as untrustworthy through a VPN service as it is through any other internet connection.
