I may not be an expert in French law, yet an analogy that comes to mind would be envisioning workers of a grocery store who've decided to go on strike. But rather than merely expressing their refusal to work, they also opt to seal the store's doors, blocking customers from entering.
Of course, customers might find the current situation unfavorable due to the absence of employees (think of barren shelves, paralleling communities overpopulated with off-topic discussions). Management, too, would likely find the situation objectionable due to a lack of employees to ensure transactions are being made legally (equivalent to the absence of moderators who uphold site rules, a scenario potentially hazardous to Reddit). Even though management might be compelled to shut down the store under these circumstances, it's essential to remember that closure remains a management prerogative, not a decision for the striking workers.
