@Daojoan#Musk briefly blocked me, as a matter of fact.
(Marc blocked me too, in response to his “It’s Time to Build” essay IIRC.)
This was back around 2016 when #Tesla first really launched its #FSDBeta wrongdoings. Musk was far less followed back then (and Twitter was far less “noisy”).
I think Musk was later forced (by court order?) to unblock a lot of people because he was routinely sharing investor information on his Twitter account - so he unblocked me at some point.
