They are planning to also block VPN providers during football matches, see https://www.techradar.com/vpn/vpn-privacy-security/la-liga-w...
They are not "planning" to block VPNs. A technologically illiterate judge has ordered it, but there are no plans nor mechanisms to enforce it.
"A _Sanish_ Court has ordered NordVPN and Proton VPN to block IPs transmitting illegal football streams" [emphasis added], that is inspain.
When talking about VPNs, it doesn't have to mean "third party VPN". You can host your own on any VPN service outside of Spain.
