SAN FRANCISCO — Twitter has refined its technology so it can censor messages on a country-by-country basis.
The additional flexibility is likely to raise fears that Twitter’s commitment to free speech may be weakening. It comes as the short-messaging company expands into new countries in an attempt to broaden its audience and make more money.
But Twitter sees the censorship tool as a way to ensure individual messages, or “tweets,” remain available to as many people as possible while it navigates a maze of different laws around the world.
