They're saying to apply the same rules to everyone, and that the rules should be based on a human rights framework. Those seem like pretty good ideals to me.
Unfortunately this is categorically untrue. Twitter does not ban international terrorists from its ranks nor does it remove regular people who say awful things on Twitter. Go for it, do a search for violent threats on twitter. See if they have banned every account in Africa or the Middle East, or Asia, etc. Even north America.
They may ban Luis CK for misogyny let's say, but they sure as hell would not ban all the Bros who use misogynistic language. Do you think we can't find twitter handles of cartelists making terroristic threats in Mexico or other places? Is that all gone now?
Twitter has a system that misses a lot but they ban regular people all the time. You can pick up a suspension for saying you hope someone steps on a lego.
