The market would only react if people were actually aware of the privacy violations. This is what the GDPR is trying to address by making data processing require informed consent.

The vast majority of people (some even on HN) have absolutely no clue how advanced the stalking actually is. You hear every so often these anecdotes about people suspecting Facebook of listening to them; it's actually more creepy that the tracking is advanced enough to successfully infer conversations without actually listening in.
