Moving the goalposts of perception
I don't know what agenda the various factions of French government have in all this, but it actually doesn't matter too much.
The net effect of this sort of stupidity suits the purposes of authoritarian nutjobs down to the ground.
Folk have only so much time and energy to protest about anything, so by putting up takedown orders (they're not going to be requests for much longer) for silly reasons, they reduce the opposition to takedowns on the stuff they genuinely want to supress.
Incidentally, forget about 'left' and 'right', this strong trend towards authoritarianism is showing its face across the political spectrum, though it's nearly always happy to use those terms to divide and rule. Sometimes this is done with considerable sly cunning, though I'll refrain from giving examples to avoid exactly this trap - they're easy enough to spot for anyone prepared to let go of thinking of themselves as left or right wing.
