I have watched Twitter cancel people for several years. A lot of the cancelling is done on women (especially gender-critical women) and most of the overall cancelling is done on 'little people,' not famous journalists, academics or public intellectuals. It's probably much harder to cancel the latter group, in any case.
Twitter itself has a penchant for cancelling women's voices by lifetime bans for misgendering and such while it allows 'minor attracted persons' to freely create connections.
