I would dearly love to return to even the 2021 era of the internet in general. 1999 would be ideal, actually. But I'd settle for most anything up to 2012 or so.
I've been trying to work out what the end date of the good internet was, and if there was a trigger event, and I'm starting to think it was somewhere between Tahrir Square (2011) and Euromaidan (2014); once the political internet became really effective, it had to be countered by those in power.
