to be honest, I think this is rushed panic action that does not really need to be taken.
getting most of the plugins is quite easy via mod-plugin-builder, that is where all the build rules and modguis come from, apart from a few commercial or closed source plugins.
the setup in https://github.com/moddevices/mod-live-usb/blob/main/plugins/Makefile can even be reused if we want to build everything while tracking their versions (auto rebuilds if something is updated)
I am personally interested on keeping the plugin store alive, be it with funding or without funding.
If company reboot does not happen, one possible plan to keep things online is to provide an alternative API endpoint that mod-ui can talk to, one that does not provide certain features (commercial plugins for one) but still allows to download plugins and perhaps update them from time to time.
the endpoint is a simple REST API, just json and binary files for plugins, so it is not complex to recreate in a new opensource form/project.
but it is best to wait a few more days until we have details on the company details.
if a reboot happens, it is likely we can just bring up the servers back online.
