What about Windows Crapware Itself?!
I am SHOCKED no one even mentioned Windows AS the Root Evil behind modern crapware with its aggravating interference, huge installation and resource hogging footprint.
If anything, the FIRST thing to do would be to TRIM WINDOWS ITSELF to what is should REALLY be limited to: an OPERATING SYSTEM, in other words, a layer between software and the actual hardware, and NOTHING ELSE, and certainly NOT the Bloated, Overbearing Big Brother Knows-it-All it has become.
Unfortunately in this puritan, politically correct age, it means basically breaking the law by installing a Tiny or Micro version of Redmond's Obeseware, and flat out REFUSING to follow their "Upgrade Brainwash" marketing policy, which, in my honest opinion, is a SOCIAL DISEASE.
I could cite many, many examples why Older and Smaller is actually MUCH better, but what do I know, I'm just an old timer who's been computing since the late 70s.
