For people upset about the 10-is-the-last-version thing, even though where they said it was not an official communication and was probably either misstated or misunderstood, the tech media picked up on it and Microsoft knew that’s what people thought they said and they did nothing to dispel that notion, at all.

So on that one, there was a good reason to think that’s what they said, and since they let that very common misconception that was actively reported in the tech news media continue without any attempt to correct, the anger is every bit as justified as if Microsoft did actually say it.
