The closed nature of MacOS and Windows means that you have no guarantees (and no audit mechanism) to determine how much the machine is passing your data back to HQ. As the post very clearly states, most people don't need to care - but someone with extreme paranoia has only one obvious choice here.

"Their equity" is the wrong way of thinking about it - the RSU schedule is fully visible up front, and in the first 2 years low RSU grants are offset by a sign-on bonus. In my case, I was told what my target TC per year was, and that is what I've received (at minimum), just made up of a varying mix of bonus and RSUs. Saying that un-vested RSUs are "mine" is like laying claim to next year's salary before having done any of the work to earn it.
When the GitHub purchase was happening, there was a lot of noise from both parties about how the companies would remain separate and GitHub would keep the things which make it appealing to developers; it therefore seems disingenuous to me to consider any of the positives of GitHub to be attributable to MS.
