The concept of "leaving" Twitter is silly.
Same with advertisers. The point of them advertising in the first place is to benefit themselves. So "withdrawing their advertising" is surely removing that benefit and hurting themselves? Well played fools, well played.
Same deal with economic sanctions - the trade deals were mutually beneficial, that's the point of trade. So whatever harm you do to the other country you do equally to yourselves too.
It's idiot policies for optics. Virtue signalling at the corporate and global level.
Companies and agencies infested with left wing ideologues.
