They are doing it to kill off competition, not because they care about privacy.
Does it matter?
Until it's Opt-In by default I don't see this as doing anything right, just doing something to get some attention.
It's not right - It is for the end user I mean but the basic idea did not spawn from a need to make right with their users. They aspire for market domination as well by impeding competition. I don't believe that this will affect their tracking though.
May just be because Max Schrems filed a complaint for the french data protection authority against the tracking id.
After exhausting all other options.
Killing competition and dominating the market??
Google finally decided to do something right under pressure coming from Apple. I can't praise enough for Apple though. Yes, of course, Apple's product is not user, so naturally its interests may align better with users. Still, this push for privacy is going to have a long term impact in the industry.
