My hope is that a lot of the more annoyed subs will do the two days and then continue indefinitely after.
Saying it's only two days makes it harder for Reddit to prepare some bad-faith counter to it (like replacing the mods and/or putting the sub back to being live).
A lot of redditors still have no idea what's going on, so even the two days gives them a chance to get caught up so they can decide if they care about it or not.
