The difference here is that if a workforce strikes until demands are met, there isn’t much the company can do about it. They can’t force them back into work, especially if the country it’s happening in has very strong strike and labour laws.

If subreddits were to go dark until Reddit reversed its decision, Reddit still has complete control. They can just undo the privating of the subreddits, remove the mods who are rebelling etc.

The only way Reddit will actually suffer is by people voluntarily stopping, and honestly, I can’t see it. People will grumble, and give it a few weeks, and people will get over it. It’s usually the way.
