What's a VPN though, just an encrypted tunnel between two nodes. For decently technical people, it'd always be possible to rent a VPS somewhere outside the country and route traffic to it.
If they're going down that route I'd expect the first service to be banned will be Tor, I'm actually mildly surprised they haven't tried that already.
It really is easy. You can not outsmart lawmakers here, if they are determined enough.
It doesn't have to be 100% perfect, just 80% plus some messaging (edit: and harsh penalties). Do you not accept this?
As to wording of the law, eg:
"A Commercial VPN is defined as a service offered to the public for remuneration that routes internet traffic through servers to obscure the subscriber's IP address or apparent geographic location, where the primary purpose is to provide anonymity or circumvent geo-restrictions."
"A Business VPN is defined as a virtual private network operated by or on behalf of an organisation to enable employees, contractors, or authorised agents to securely access the organisation's internal network resources; connect geographically separate premises of the same organisation; or comply with data protection or security obligations."
If they're going down that route I'd expect the first service to be banned will be Tor, I'm actually mildly surprised they haven't tried that already.
