The article doesn't specify, and corporate VPNs can be configured for either full tunnel or 'only tunnel LAN', depending on if they need external users subjected to the internal firewall.
And besides, distinguishing between corporate and internet proxy VPN would require effort from whoever ends up enforcing this. Neither law enforcement nor ISPs are going to do that, as it would reduce this new revenue stream of 'fines for all anomalously constant TLS traffic.'

Pfft, I got one with TODO_Obfuscate_URL. I wish I saved it.
