The reason: because it was easier, it allowed corporations (especially Microsoft) to give the appearance of making social change, and because it distracted us from dealing with the real issues. In other words, laziness.
And you know what, if you're firmly on the progressive left, as I am, that's no big deal. It's annoying, maybe it alienates me from taking part in social action. But it won't, for example, change who I vote for.
However, we (the West) live in a period of history balanced on a narrow edge between social progression and social regression, with all manner of bad actors waiting on the wings to take advantage of our slipups. And this was a slipup, no matter how well meaning the people who pushed it through were. This, and many, many other small annoyances, were in all likelihood what it took to push a significant number of people to change their vote in the recent election. It's not the only reason, perhaps not even the main one. But any change is significant when you're balanced on an edge.
