Changes to be less preachy, idealistic, remove non-public quote and improve focus

[girifox]

I don't know who the original author is of this 'MS workers statement' even though I would identify myself as being part of that community. I did not like its tone and believe my proposed changes edit it to a more collaborative tone.

I oppose the merging of this PR generally. Most of the changes dilute the impact and message of the letter. While I understand the concerns of a "preachy" tone, I don't think a less impactful letter is appropriate for the level of these concerns.

I particularly oppose the removal of the part about the impact on "Global South and Black and Brown communities who are disproportionately affected." I think people that Microsoft affects need to be centered and not removed for a generalized "everyone." It weakens the letter dramatically.

Edit: I want to be clear I don't think the letter itself has a "concern" of being preachy, just that I understand there will be some calls to tone-police the letter.
