Microsoft-hired contractors listening in through Xbox One Kinect, Cortana and Skype Translator

It appears that Microsoft isn't the only one involved in the recent privacy violation incident through the personal assistant service, like Siri, Google Assistant, Alexa, etc. Who knows the motive and reason behind this? Plus, you're going to disable Siri/Google Assistant on your mobile device over this situation, though?
To train the AI through data collection through various products like Cortana, Kinect and even Skype Translator engine seems to be a dangerous excuse or a lousy one. So, it looks like Microsoft might have lied or something that the Xbox One Kinect wouldn't collect data when the console was revealed at the time that the data collection thingy through Kinect resumed sometime later. I don't know if this may seem accurate or not but then again, who the hell uses Cortana on their computers and Xbox One anyway?
To disable Cortana completely from Windows 10 will be no easy feat even when there were feature changes in Windows 10 1903 update which separates Cortana and Search feature as well as the fact that Cortana will be on the Microsoft Store in the future. It may seem like an acceptable change but don't go asking us that don't we even use Cortana at all or something. The worse thing is, there's still lack of support for other unlisted countries but it shouldn't be difficult asking Cortana something in the same vein you ask Siri or Google Assistant which is obviously more popular.

Cortana Button for Windows 10

A third-party hardware addon for Windows 10? You could have activated Cortana easily with Windows key + C for communication or perhaps you might have turned that off completely for the sake of security! I don't see the point of this on devices running in Windows 10 but I guess that the only useful thing is that it can be useful for embedded devices running Windows 10 on the car or something.
This device by Satechi uses the Bluetooth 4.0 LE technology and promises 2 years of battery life. All you have to do is to press the button to begin communication on the go but that doesn't seem to be the point when you already have a smartphone/tablet having Cortana in there that you can activate it easily.
And this is more or less your opinion of whether this Cortana Button is pointless or not but when it comes to Android or Windows embedded car devices that have the personal assistant feature that can be activated locally without the need for a phone which can also be done the same local way, this is where the Cortana Button is becoming really pointless for me when you can already activate Cortana locally on your computer, tablet, smartphone and other devices that support personal assistant feature without the need for USB, Bluetooth or network connections. It's a wonderful waste of everything spent on making hardware addons like this when you can actually activate personal assistants locally. The only place that's Intranet-ish in terms of the way the personal assistant searches for is the military network. She/he may have known whatever that goes on in the places one military side is in but she/he can't know anything from the enemy side.

Foursquare with Cortana

Foursquare is some social application/service I had used to record down the places I visited although I don't record down immediately the moment I enter various places to be frank when doing the Check-In feature so expect the timing to be damn late but we should be able to admit or whatever we had done there. Now there is Foursquare mixed with Cortana but I don't know how will she help us out in certain things once we have visited various places. Will she describe the new places we visit for the first time as well as to tell us on what to do there?
Also, I don't know if there's a similar answer to this for IOS and Android but even then, I don't use the voice command thingy at all. Maybe I can straight away turn that feature off no matter what as I may be shy to use it.
