Disconnect was co-founded by an ex-Google DoubleClick (ad) engineer, and hired an ex-NSA (dragnet surveillance) engineer. There are tracker-blocking adblockers for every platform that aren't made by people with anti-privacy backgrounds.
And SELinux was designed by the NSA due to the 10 years or so of the Flask Security Architecture and made it into Linux. Under your tinfoil hat, does this mean that Linux is totally compromised?
I didn’t mean to imply that Disconnect is compromised. But I think the background of the team would prompt a fully open source product on every platform in order to establish trust. Until that happens, why not use a blocker whose team does not have an anti-privacy background? (The Disconnect website has said “Code available soon” for the apps since at least March 2015 [1])
All three implement MAC (mandatory access control) similar to SELinux, but the context bits in SELinux are pretty much standalone for information assurance (DoD Rainbow book series has more info). Note my username comes from my SELinux experience :)
