There's a keyboard shortcut configuration for Illustrator users. Modifiers too, I hear the difference between ctrl and shift really hurts moving between programs.
Not a problem since 1.1
I briefly tested that with 1.1.2, at least r for rotate doesn't do anything.
FOSS is supposed to serve people, if your system can easily accommodate that, I see absolutely no reason not to other than some ideological desire to be different.
If someone that has been using Illustrator for years tries Inkscape and goes "Why the hell would it work like that, that's insane", then gives up, that doesn't serve that user nor FOSS, and they go back to paying Adobe.
