So many people complained that once they changed a preset, they couldn't get back to 'zero' with any certainty. The presets are there so people can have starting points. They can also see how certain parameters affect the sound. I also like having them so I can dial up a sound similar to plugging in a new pedal.
The Kemper Drive proved that 'loose' presets was a pain. It was frustrating as all hell for me.
Can't please everyone, nor should you try. But calling CK and Company arrogant for doing something 10+ years on that others have done since before Kemper existed is puzzling. Others might call it catching up.
