Valid question. Hate to say this, but if most subs reopen after 2 days, we're essentially handing reddit bosses an easy win. It's like protesting with no terms, and instead merely creating a brief storm that'll pass and quickly be forgotten. Might as well throw eggs at a tank with that thinking.
The only way this protest works, is if subs stay dark with no deadline, and terms that must be met to end the standoff. That's how these things work. That's how it's always worked.
