Of course they are mostly older articles; the protests have dwindled to the mere hundreds, down from over 300,000 nationwide. During the height of the protests, they were covered extensively by the BBC -- it's misleading to criticise their coverage with "BBC in 2019".

The BBC's latest article, which I linked, was 14 July. The BBC aren't alone in this: it's also the most recent French protest to be covered by Reuters, CNN, and other major news organisations.

The Hong Kong protests are still a major, significant event. The French protests have dwindled and are no longer as relevant.

That's simply because they are much fresher. Otherwise the Israel/Palestine conflict would be on the front page every single day.
