Social media is now less town square ("Speakers Corner") and is a information weapon. I think Musk hoped to use blue checkmark attribution as a means of putting posts to the attribution test, and I believe he underestimated the appeal of bias enforcing anonymous posting. The tension between freedom of speech and dog whistling is unresolvable and I would argue different times call for different approaches. Its clear state and state-sponsored actors are abusing social media liberalism to the great detriment of Western values and stability. Its clear these same actors do not permit the freedom of communication they abuse elsewhere.
By way of example, its fascinating the LGBT+ community is so tightly allied with radical Islamic voices against the LGBT+ friendly country of Israel. Its fascinating because of network effects that drive this apparent alliance, whereby a group likely to be outlawed (or worse) identifies with its avowed oppressors.
We live in very interesting times.
