@flancian "authorized fetch" is part of what you're describing, and I hope its adoption continues to increase.
As for "you can still see the content on the web", sure, but there's a wide zone between "technically impossible" and "absolutely trivial to do" – surely you agree that putting *any* friction in the way of the bigots who demonstrably exist on Threads will reduce the amount of harm caused, even if not to zero?
