Can someone please tldr me what digital public goods alliance means and how peertube can benefit from being recognized as a digital public good.

From what I can tell, it is UN affiliated/related project where basically it tries to make countries integrate these digital public goods in their country's ecosystem/ work on these (products?)

Is there any amount of sponsorship money that come with this classification or more tax benefits?

Or does UN (thus countries who fund UN) itself fund DPGA?

I find this idea fascinating now thinking about it if that can be the case, for these countries a few millions or even billions collectively might not mean much but it can mean a lot towards open source and digital soveriegnity in my opinion too.
