This was not a small thing to change. It was a minor thing, in itself. But the actual process of changing was huge, and took months of energy and pointless discussion from millions of people. I would guess the change could be counted in the millions of people hours.
I'm strongly in favor of progressive social change. But when even the smallest of change takes this much effort and leaves people frustrated and alienated, we should not be focusing this much effort on insignificant changes. It's like trickle down economics - hundreds of minor changes like this will not trickle down into large changes. Most likely the opposite - they'll alienate and infuriate enough people over time to cause a societal swing in the other direction.
If we're gonna put effort like this into bringing about change, let's make it meaningful, something that effects our daily lives now.
But also, small things do have to change. If nothing changes, the status quo remains, and the status quo is stacked against many people. (Because of gender, race, culture, wealth, location, etc). It's easy to say "focus on the big things" but the small things can change along the way too.
