'By the last day of August 2020, 310 employees had added their data to the spreadsheet. Microsoft employs more than 150,000 employees around the world.'
150,000 employees are not all L5x-L7x leveled or engineers. Not everything in the world gets leaked, so we're only addressing one leaked spreadsheet - of many.
Your original claim was that people get fired for this within the week. I refuted that I don't recall any sort of event. There weren't announcements for mass firings of 310 employees. If you have more details on this, please share. You seemed very convinced of your initial claims on how Microsoft reacts to contentious acts by employees against the company, so I imagined it must be evidence based. I really would like to know.
You don't say.
