It should be clear that this isn't "just" trying to be mission focused, that was very eloquently written and timely, but it is failing because it is a reaction to internal issues which wasn't clear to the rest of us. And as such it has stirred a hornets nest that also no longer wants to keep things inside the company.
Many of the people it has stirred are also people that have been fighting for more inclusivity and also identify as part of underrepresented groups. People that feel like their voice isn't loud enough because they are so few inside the companies. This doesn't represent everyone in underrepresented groups, only that there is a significant overlap in the goals of inclusivity and people that want the company to be more welcoming by speaking out against inherently political nationalism, which the company doesn't want to do.
I'm not offering any solution only observation.
The latter is the more visible one and being targeted by this, and in my opinion rightly so, because that behavior (attacking others) is toxic and helps nobody.
In other words, exactly the toxic group of people that this is trying to remove from the company.
