I fully agree with this article. So much stuff on OS X is neglected. The recent releases only focused on minor updates of the UI, while many components in the lower layers have not seen updates since OS X 10.6 Snow Leopard (2011). And if they do, it gets as bad as the disaster around discoveryd introduced with OS X 10.10 Yosemite [1].
On a small sidenote, Apple's ticker symbol is actually AAPL, not APPL. I hope you did not invest into the wrong company's stock!
