Some people just look for reasons to complain, especially when speaking about user options on the watch. How can something be intrusive and against the user's wishes, when it is ultimately up to the user whether he or she wants option x on?
If you don't care about the new walk feature, move on to something else meaningless in your life to complain about. The Apple Watch doesn't revolve around what any one person wants or expects all the time.
Some of these comments are things an adult would expect to hear from a kid in kindergarten or first grade.
The only thing I am sorry for is that this is another symptom of people’s inability to be in solitude, with their own thoughts, even in a natural scenario such as walking.
Not this functionality’s fault, but this won’t help in the long run. Also people have to realize - and I do know it’s difficult - that they should workout/walk not because of a voice, but because of themselves. Oh well.
