Until it turns itself back on during an update. Or hey implement another version that has its own off switch buried somewhere, etc.
It’s bloat and hassle.
You shouldn’t have to do maintenance on a brand new Windows install. Set preferences and install apps? Sure. But expecting everyone to go through a checklist of shit to turn off? Nah. That’s user hostile and so tedious.
Checklists and debloating procedures like that can feel like something an expert would do. And can feel like what a good computer user should do, but that’s a limited mindset that is a niche among all Windows platform users.
Warning, car analogy:
Imagine if you bought a new car and had to scrape a bunch of advertisement decals off it. And you have to remove unneeded features like spoilers that are dragging you down. Oh, and randomly in the middle of the night the dealer tracks your car down and applies new decals that you will want to scrape off your windshield when you get a chance.
