If only it fading away didn't mean instead of being able to treat Twitter as support there's no place to get actual support from a lot of companies. E.g. Google sent me a promotion for a Nest camera if I bought their subscription, and instead of a camera I've had their "support" read the same script about how they'll fix it within a few days since November. At least if I used Twitter as support, other people would see the issue that didn't get resolved.
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.
