I imagine a programmer unaware of anything that's going on writing the code for the latest, greatest /r/place feature, getting so wrapped up on the project that they don't realize it's not April anymore, smiling proudly and announcing loudly when they deliver their pride and joy. Only to see it be transformed into a big penis that shoots out the letters API.
I supported the blackout not just because of the sudden changes to third party API usage (I only use Old Reddit so it does impact me less) but because this was clearly a change that severely negatively impacted the moderators on Reddit. The moderators on Reddit are unpaid and the work they do is mostly deleting spam. It's not fun stuff and we are fortunate to have so many volunteers (even if some abuse whatever little power they have). They were the ones who organized this blackout. Reading some of their complaints, I empathize greatly. So even if the API changes don't get reverted maybe the blackout gave Reddit's corporate heads a moment's pause to actually do something to help the people who do all of the work for them.
So even if things don't get reverted, perhaps there was something positive to this whole event.
Also, being off Reddit for days has been really nice. I feel better, not being there. I might stay longer here.
