So no, there are very, very good reasons, IMO, to stay on Windows 7 or 8.1 (where this problem didn’t exist). I actively recommend others not to switch to Windows 10 because of this. Of course, YMMV!
Disclosure: I work for Microsoft.
To your last point, I would say I am ready to accept it from anyone except an advertising company whose only primary means of making money is by sifting through my personal data and spying on my online activities. With MS, I have little doubt that they "would if they could", but at-least for now, they wont, since they're making more money selling actual products.
You don't have to install them, installing only security updates was still am option last time I checked it.
On top of it, even if you install them they can be turned off completely, and they are turned off by default, contrary to Windows 10 where you can't turn off telemetry.

Yes there are. Windows 7/8.1 performs better and more snappy.
Windows 7 (and 8.1 with a classical standard menu extension to hide "modern" parts) has a more consistent interface unlike Windows 10 ui which is all over your face with inconsistent menus, colors, sizes etc. stinking out of everywhere. Half baked app choices with some modern and some classical apps and you don't know which one will open from which settings menu.
Forced updates whenever Windows feels like. There is no option out because pesky users can't be trusted.

The only thing stating the upgrade offer has ended is "The Windows 10 free upgrade through the Get Windows 10 (GWX) app ended on July 29, 2016." Which is technically true, but the free upgrade is still offered through other methods.
Contrary to popular belief, there is no good reason to be running Windows 7 or 8.1. All of the telemetry anti-features were backported into those versions, Windows 10 is inherently better at security, and trust me, if I can get the legacy software I have running at work running on Windows 10, legacy app issues aren't a problem either.
