GraphpostgresQL is no longer maintained and hasn't been updated for many years.

That's the most rational plan. However pharma companies can just buy media presence, create panic and criticize their authorities(this happens to Bolsonaro in Brazil for example). Then riots begin, generating a whole other set of problems for the authorities who have no other choice but to save their neck and concede pharma companies demands.
Control the media to stop the panic, that only worsens things with a nocebo effect. Gradually remove restrictions since numbers are going down anyways.
No, you can get the installer directly from the NVidia website, but only for selected platforms. If you're on a different platform, you'll have to wait until somebody ported (read: hacked) the release (or do it yourself).
