At the end of the day what is or isn't "Too Hard" is subjective, it is an opinion. The only opinion that counts on the issue is SE's who are likely making the decision based on metrics. They want a certain % of groups that attempt the content to pass it, and they want the groups that pass it to pass it in a certain amount of time. If they're nerfing something now it's either because fewer people are passing it and are passing it more slowly than they want or the nerf was always scheduled as a planned part of the content's lifecycle. I'd personally suspect the former more than the latter, but only they know for sure.

At any rate they certainly didn't do it satisfy whatever your particular agenda is, or run afoul of whatever your personal hangups are. They're looking to make sure the content they produced is performing in the capacity they wanted no more no less. "Git Gud", "Tears of Raiders", what? That's just so much digging for a negative narrative that really isn't there.
