The privacy concerns. Also, older people like me don't enjoy things constantly changing, so having more control over updates is appealing. I despise Windows 10, enough that it prevented me from buying a laptop, until I eventually found a vendor willing to install Windows 8.1, which I merely dislike. I wanted Windows 7 or was willing to try Mint. However they are not available, "no drivers" and so Linux is dead to me.
