When I worked at a web hosting company, it certainly felt like Linux got hacked as much as Windows.

The solution is not that everyone on Windows switch to Linux, just that some of them do. You said it right there: Linux is more secure, right now, not because it has fewer holes in it but because the incentive to find those holes is much less than with Windows. Seems like a good enough reason to switch for me, just don't expect it to last forever.

Farmers have known for centuries that diversification increases security, for a small cost in efficiency.

And THAT is my main objection to GMO / seed standardization
