For a minute, I thought your comment had simply trailed off without finishing your thought.
Then I realised it wasn't "Microsoft Skype", but rather, "before Microsoft, Skype had..."
I see, thanks for the info. Comma setting in English is rather unexpected for me. It works different in German, but I'll try to adapt. Maybe in English you would also say "end-to-end encryption" rather than "end to end encryption", is that correct?
Both are commonly used, although "end-to-end" is correct as it indicates a compound adjective - a phrase acting as a single adjective affecting the noun ("encryption") that follows it.
That's probably because before Skype, Microsoft had Ballmer.
