> The point here is that productivity in old Microsoft was far higher
That sounds virtually impossible to prove between unequal situations, and especially "far" makes it seem like an exaggeration / tall order (productivity between people isn't like wealth or popularity: some things change by multiple orders of magnitude, but how hard you can work doesn't, especially when averaged across thousands of employees), but to be fair I didn't read the whole fourteen thousand word source you added so I suppose I can't say for sure.
