I tend to agree.

Nevertheless, some unknown implementation can have bugs and things can go wrong and there's nothing you can do about it, short of "rebooting" or d̷o̶w̸s̸i̷n̴g̸ ̴t̶h̸e̷ ̸h̵a̵r̵d̷ ̵d̷r̶i̴v̶e̷ ̵w̶i̴t̸h̷ ̸̞̺͠h̵̺͙̎̍o̸͔͠ͅḻ̷̀̇y̵͚͍̎ ̷͉̅̅w̸͎̔a̷̧̫̒́t̶̼̉̓ę̵̾͗r̶̫͑͑ ̴̣̿͒(̷͙̎a̸̬̺͝͝n̸̞̓̓d̴̬͌̍ ̸͇͕͌͝s̷̡̯̓͝u̸̡̳̇͝b̴̳͜͠s̷͍̘̽ë̵̜q̷̝͐̄ȕ̵̞̐e̷̲̠̐́ń̴̨̙͝t̸̛̬͝l̶̮̔͠y̴͕̪̑͝ ̵̖̆ḃ̴̪̟u̶̢͓͑̌y̵̜̤͌̏i̵̦̋ň̴̨͚̀g̸͓͑ ̴͍̬̽à̶͜ ̴͇͔̓n̴̬͂͜ì̷̢̛̯c̴̤̖̈́e̶̼̫̐̊ ̵̹̏͝f̸̙̀̑r̷̪̩͆͆e̸̤̫͛͋s̷̢̙̏h̷͇͔́ ̸̭̆͝N̷̰͗͛͜V̶͇͒̚M̸̟̍͜ě̷̛̟ ̸̢̞́͝a̷͙͔͒͒n̷̻͇͝d̸̘̥͌̾ ̴̜͓͑p̷̬͑͊ŭ̸̮̏t̸̲̀t̴̡͚̽í̶͎͓̑n̴͕̘̒̈́g̴͓̰̓͝ ̵͓̎a̴̻̼͗ ̷̦̍̈́s̷̥̅̈l̴̝̂e̴̞̅͊ḛ̴̊̅k̷͚̕ ̵̛̼̬͗D̴̻̾̽e̵̙͂̊b̷̝͘ī̵̢͇ą̵̂n̴͖̑ ̶̼̚h̴̼͂͑e̷̲͆̆a̵̡̋d̸̢͔̈l̶͕̍̍e̸̛͕̙̒s̶̞͔̀͠s̸̯͖̕ ̵͍̦̈́̉ ̸̨̨̓i̸̙͖͗̌ņ̶̯̍s̸̡̖͗̇ṯ̷́̒ä̵̦́̎l̶̼̄l̵̨͊̊ ̴̳͑͗ó̵͎̅ǹ̴͈̚ ̷͖͊͝i̷̠͇̊t̷̼̞͒͘)̵͎̤̔͌

Well not spyware per se but over the years they found over and over bugs which are really just highways left open in your system ready to be exploited. But to be honest that's not limited to windows.

Yeah, if I were Microsoft I would implement spyware in a way that is least intrusive to the user experience. Prioritizing the telemetry data using QoS would only incentivize users to find ways to disable the telemetry, while providing no benefit to Microsoft. What's the use for them receiving the telemetry data slightly faster, it's much more important to them that it arrives at all
