Being non-free and non-auditable, including proprietary SDKs that can gather tracking info/IDs, connecting to Facebook (even when the app is something other than a FB client)... Stuff that's quite comparable to what the video is talking about.
Indeed. I don't have a Facebook account and yet various apps on my iOS devices still attempt to connect to graph.facebook.com (amongst other servers I'd rather they didn't, e.g. flurry).
