This little bit is a gem.

"Twitter may share this information with these partners before you’ve signed up for Twitter (e.g. when you first open the app before creating an account) as disclosed prior to download in the Twitter app description in the App Store and Google Play, but does not offer you control over this data sharing until after you’ve created a Twitter account.*"

If I don't have an account, how could I have possibly have agreed to anything? Do the permissions on the phone give the app everything about me as soon as I download it?

What about situations where the phone comes preinstalled with this crap? Does the act of buying such a phone automatically mean Twitter now knows where I live and my taste in pornography?

fyi google services does the same, google just dont openly sell to others, rather using it themselves.

well, I trust Alphabet Co not to "share/sell" our data just as much as the laws put in place to protect our privacy are doing a decent job... which is to say not at all of course : /
