Uhhh... Is the OP thinking they are doing maint just for fun and have no valid reasons for doing it? SE just likes to pay it's programmers to fart around and take down the servers just for the hell of it? Interesting.

Logically: Servers being down = less money the company could be making. Also time spent implementing these updates and bug fixes. Pretty sure they are doing maintenance for a reason other than just to make everyone upset for funsies.

No one likes maint. But it's ok. Keep calm. The world isn't ending. And if it is, make sure you have your towel.
