I don't have anything to say for Babel, as I'm not a user of it. But I remember the anger of the Angular community as Angular 2 was announced. No one could believe that they would eventually choose to leave behind Angular 1, that they'd have to nearly rewrite their apps to be compatible. This made people angry. I believe they might still be. And I don't see a point like that addressed in the story.
I don't have an answer for you on how to fix this. There are many people that consider the A2 switch to have been necessary, so "don't do stuff like that" isn't necessarily even an answer.
But my point stands. People get angry, for better or for worse. Logically or irrationally. You can't just "call out" that behavior and expect it to get better. You need to better understand and empathize with those people, and work with them.
I don't believe this piece is helpful. I think it paints with too widely a brush and ignores the legitimate criticisms that the community is making.
