One thing I don't understand is in one sentence he states,
Without unencrypting the telemetry packets Microsoft receives, we're not going to know exactly what data it receives.
and the very next he says
But they're small and relatively infrequent, so are unlikely to be packed with your personal data
So the assumption is that it is unlikely that they are collecting personal data, based only on the size of the data being sent? Again, I'm not one that thinks MS is doing such, but it seems a lot of people are challenging those who claim MS is actually collecting to prove such, which they cannot. However, in a counter argument, I don't see a lot of people proving that MS
isn't collecting private data as they also cannot.
This author, why I respect his work and effort, is making a pure assumption that the data being sent is not private data without actually seeing said data, but rather judging its size. Not saying the are collecting, but if you cannot fully prove they are not (which would be impossible unless working from the inside of MS I suspect), then you cannot say, at least beyond the shadow of a doubt that MS isn't collecting private data. Regardless of the size, that doesn't prove they are not collecting private data to some degree, but it also does not prove that they are.
Remember, the Earth was once flat because it was assumed and accepted, until actual proof was presented to say otherwise. Until MS officially comes out and details these connections and that the data being sent actually contains we all, both those claiming foul play and non-foul play, can truly only assume what is or is not occurring.
