“Sailfish OS, as a non-American, open-source based, secure mobile OS platform, is naturally an interesting option for different players — currently the interest is stronger among corporate and governmental customers and partners, as our product offering is clearly focused on this segment,” says Jolla co-founder and CEO Sami Pienimäki ."

Like how you say "open source based"
It either IS ...
or ISN'T ...
open source.

And Sail ISN'T classed as open source.

(I know the same old argument ...and I am not being critical or over-the-top concerning the finer points regarding "must have" finicky philo of things being open source ...and all... but nowadays more than ever ...if I can do without black boxes in my os ...I go without .
I use Android ONLY for what I must ...and use my buntu phone for everything else)
