"Punishments" vs "consequences"
This argument is disingenuous.
"Consequences" implies naturally occurring cause - and - effect event chains. Cancellations are punishments deliberately enacted to target an individual for their speech. State / social / individual level actions against a person are more accurately described as punishments, not consequences.
Reducto ad absurdum: If you say "You are free to say anything you want, but if you say something I don't like I will punch you in the face" - is this free speech?
