According to the New York Times,

The legal scholar, Benny Tai, was convicted of public nuisance charges last year and sentenced to 16 months in prison, but he was released and remains on bail while his case is under appeal.

The university had faced widespread calls from members of the pro-Beijing establishment to dismiss Mr. Tai. But his supporters argued that dismissing him would undermine academic freedom that has already been imperiled by a new national security law imposed by Beijing.

Let’s put it this way: Academic freedom means zero in Hong Kong now that the iron fist of Xi Jinping has come down hard.
