If you don’t use Bing with Edge, Microsoft will tell you your computer needs repairing.
They are not wrong.
To mend your machine:
- Ditch Windows
- Install Plasma
- Your computer is ready.
You are working with hypotheticals. We cannot judge what the reasoning is. We can only judge what it is. It may have been done with good intentions as you say. Given MS’s track record, highly unlikely, but either way the fact is MS is telling its Windows users that anything that is not Edge and Bing is damaged or malicious. That is anticompetitive bullshit (intentional or not) and FUD.
