FTA, on why this is important:

Next is that this is an operating system upgrade free of commercial and marketing constraints and drives. Compared with, say, an iOS upgrade that trumpets the addition of a search function or blares out a proud announcement that they broke maps because Google kissed another boy at recess. Or Windows 10, the 1968 Democratic Convention Riot of Operating Systems, which was designed from the ground up to be compatible with a variety of mobile/tablet products that are on the way out, and which were shoved down the throats of current users with a cajoling, insulting methodology with misleading opt-out routes and freakier and freakier fake-countdowns.

So true. :/
