Like with so many things, it’s not the thing itself that’s the problem. It’s the forcing.
If Microsoft had presented the advantages and given me a choice, I may or may not have decided to upgrade. But the fact that they are trying to force the upgrade without my consent, means that they believe I shouldn’t be allowed to decide what happens with my own property.
In my opinion, that is crossing a VERY serious line!
Oh, but it isn’t your property - it is Microsoft’s!
Read your EULA, you can use THEIR software at THEIR *sole discretion*.
You only paid to use THEIR software, which isn’t guaranteed to do anything, and which they can change at any time.
