I think data harvesting for AI is the real reason Twitter and Reddit want to limit access. Even I was thinking how easy it would be to mine both sites. It sucks because that’s the end of the (quasi) open web.
It's not a lot of sites (yet), but it's making the web get smaller, and worse, it's affecting the most useful and interesting parts of the web more than the commercial stuff.
It's kinda on us to ensure that it's only in the interregnum that we have the morbid and dysfunctional symptoms.
