The article is not very clear, but my interpretation is that this is about the e-mails sent from Proton Mail, not users being able to access the Proton Mail web site.
A VPN won’t help you if the server for the recipient of the e-mail drops the e-mail.
So, basically imagine that all Internet service providers in India have to block any e-mail from @proton.me and not deliver them. I think that’s the idea.
Can India even block ProtonMail if the users also have ProtonVPN?

could they theoretically just block protonvpns ip range at an isp level?
If you start blocking VPNs you are cutting off your country from most telework/outsourcing because corporations need VPNs to their branch offices.
This is an acceptable trade off for Russia, probably not for India.
you dont block off all vpns, the ips proton vpn uses. vpns in china work the same way… not all vpns work in china, but they do exist
A state level block on protonvpn would be at the IP block level based on known, published exit nodes.
Corporate VPNs are point to point and would not be impacted
I think protonmail can work with tor
