Reversing are explicitly allowed in EU government as other based human laws.

I mean, EU have a much more great priority then Skype TOS.

If someone will add to Skype TOS "and please dont breath or dont go to toilets during use of our application". It will have zero effects in legal meaning. Because it break upfront law and United Nations based rights and etc.

tldr;

They just try to fear you with "dont do this" thing.
