Microsoft enabled Do Not Track by default. Advertisers said they would ignore it for this reason. Most of them never respected it. Apple removed it from Safari years later because it was used for tracking. Mozilla removed it from Firefox years after Safari. Chrome has it even now.

That was the missed opportunity. Had the EU stepped in and said "I'm sorry, the user expressed explicit intent to not be tracked and you're planning to ignore that? How about that's a fine?" it would have survived.

But they weren't prepped to take action yet.

Microsoft made the user expressed intent and the user expressed no opinion look the same.

		That doesn't track (pun not intended). It's a binary state so either side has to be the default, they just changed which side the default fell on. Prior to the change no opinion expressed and expressed intent (in favour of tracking) still looked the same.
