From the news:
"...we want to make Raspberry Pi more open over time, not less."
"For the last six months we’ve been working closely with Microsoft to bring the forthcoming Windows 10 to Raspberry Pi 2"
From a comment:
I’m sad to see Windows 10 as a “selling point” though. This community should not be supporting restrictive proprietary software… The Pi is about tinkering and making things while Microsoft is about marketing and spying.
From an answer:
"But I suggest you rethink your comments about MS, spying is going a bit far, don’t you think?"
