I did not mean to imply that the actual M1 will be used in data centers. Apple is quite popular among developers and its also a trendsetter which will probably lead to other computer manufacturers to adopt ARM for personal computers. So having more people use ARM on their personal computers will lead to more ARM adoption in the data center.
I believe interpreting statistics from those surveys in this way isn't fair. There are so many developers around the world but the pattern of value/money generation by them is not uniform; in other words, a small percentage of developers work for companies that pay the largest share of server bills and penetration rate of macOS devices among developers of top companies is probably higher than average.
(I'm not implying that developers who work on non-macOS devices, make less value because your device doesn't have - nearly - anything to do with your impact. I'm just talking about a trend and possible misinterpretation of data)
