Consider why we care about security in the first place:
- We don't want our private data stolen
- We don't want a malicious program stealing our electricity and computing resources
- We don't want adware injecting advertising into our browser toolbar, homepage, email client, etc
- We want our family to be able to safely use our computers without having to worry about them falling for scams
- We want peace of mind
Almost all those points are basically the same thing repeated differently:
We don't want somebody else mess with our computer, but that "somebody else" almost always is 3rd party - so not you (user) and not Microsoft (vendor).
Ads from vendor aren't considered as a security issue (unless very edge cases).
They are annoying, but in the principle they aren't security defect (unless badly implemented)

Please define security in a way that excludes all possible classes of "third party doing things on your machine without your knowledge or consent"
