From Computerworld:
Commenters have scoffed at Microsoft's backtracking from a widely-criticized practice to trick users into upgrading to Windows 10, arguing that it was nothing more than a public relations ploy employed when the free upgrade was just weeks from expiring.
"People have been complaining about GWX [Get Windows 10] since last October. To finally admit there's a problem 1 month before the end of the promotion (and it'll be another week before everyone has this update) is really sad," wrote someone identified as Rossco1337 on a Reddit thread Wednesday.

"[Microsoft] probably [did this] so that years from now, the vague memory will be, 'Microsoft was a bit pushy, but in the end they backed off and gave people choice,'" added illithidbane in the same discussion thread. "They want it to have been pushy for as long as possible, get as many upgrades as possible, but end on a 'high' note."
They do have a point, but I have the feeling that there's a little more to Microsoft's latest move than simple PR.
