It is more a security nightmare than an environmental one. I have no idea what MS will do when 20% of online computers no longer recieve security patches, but most people won't throw out unsupported machines. What is also interesting is that somehow this is a giant outrage (6-7-8 years of support, a few more if you consider that for a new 11 install the reqs are not as strict), but Apple has been doing this for basically the last 10 years for Macs more or less.
