That does not help if you’ve identified yourself to the app. E.g. if you logged in via facebook, then any in app trackers can link your activity to your facebook account.
I recently installed a dating App that required authentication via Facebook or SMS. I chose SMS (because screw Facebook). But lo and behold, it turns out the App developer uses Facebook's SDK for the SMS verification anyway. And since FB has my phone number from the two factor scam [1] it pulled, it really made no difference.
This is relentless from Facebook. Consider the fact that they own WhatsApp, it is pretty much "no where to hide" scenario here even for folks who have no Facebook account. Jaque y mate.
Oh, how I wish WhatsApp was an independent company. I am sure Jan Koum and Brian Acton think so too [0], despite making billions off its sale.
I’m sure if they have to choose, they’ll still take the billions. No shame in that, but to pretend otherwise is silly. As if FB is pure evil and everyone else is amazing.
Oh they definitely are and they keep reminding/proving this every chance they get.
> everyone else is amazing
Trackers and advertisers have built a cancerous nexus that we cannot shake. We have every right to think they are the scum of the earth, and if they want to prove that they are not, they should give OUR data back to us. But they don't. Scum of the earth. No words will change this, only actions. I am happy with GDPR because those scums are finally paying the price for their actions. I am not in favor of companies closing and people losing their jobs. I am also not in favor for scums to ab-use MY data.
Not cool.
