If you indeed work for Swisscom (and I hope you don’t) I’d take my buisness elsewhere. You make Swisscom soud like a silly little company. I’m pretty sure this is not what they want to be perceived as. I personally didn’t touch a Window machine in more than a decade, and as a user of both Mac hardware and Linux, I have enough alternative to myCloud to take my buisness elsewhere.
I find your answer very unprofessional.
