Really useful networking efforts, and their opposites.

My  favourite group currently working on internet stuff around the ietf is 

GAIA which is delivering lots of useful information about shared initiatives to provide meaningful and relevant internet access and services (see especially work on affordable community networks, and reducing misinformation, e.g. on covid in the minutes&slides linked above).

In contrast, the race for 5G, and now even 6G is driven, it seems to me, almost entirely by greed and a nlatant disregard for anything remotely sustainable or fairly offered (as per, William Gibson's "the future is already here, it is just unevenly distributed").

For example, we were looking at various mobile apps for covid-19 that might help mitigate the pandemic, and concluded that very few would be in the least bit viable in the developing world.  The GAIA folks are heading a long way to helping with that. Quite frankly, the 6G folks are going the opposite direction.
