It's why GDPR came into being, and California's recent data privacy law. We have no reason to have faith in these companies to keep our data safe, or to use it properly. After 10+ years of having our credit card numbers, social security numbers, emails, passwords, and so on leaked again and again, I fail to see how one wouldn't have trust issues at this point.
I never said you can't have trust issues or that GDPR isn't necessary, I'm saying neither of those implies they are invading your privacy when they show you ads based on your emails. This should be pretty clear?
Yes, and if they aren't, you wouldn't be able to tell either, so all that means is you're willing to recklessly make unjustified accusations to defame a company without actual evidence.
