Facebook had a post up, recently, that the government of Singapore didn’t like and of which that government disputed the truthfulness.
As a result, By Order Of the Singapore government, Facebook added a notice—a “label”—to the post:
Facebook is legally required to tell you that the Singapore government says this post has false information.
For a wonder, Facebook didn’t take the post down, nor did it make any effort to “correct” its content. Instead, it posted the notice, letting readers decide for themselves…whether they should take seriously the post or the notice required by a mendacious government.
Of course, I am assuming a motive for Facebook’s action.
