I own a Galaxy Note 2 and decided quite soon after I would never buy Samsung again even though I think it is a great piece of hardware. The issue is they promised to release sources for certain drivers and never actually did, CyanogenMod said they would not officially support the device[1]. Samsung feel like an anti-consumer company, them pulling a stunt like this would not surprise me[2].

[1] Thankfully they did just recently release a stable version.

[2] I also made the same decision about Sony years ago when they released rootkits on their CD's.
