Facebook sued over illegal collection of user data

> The suit further alleges that Facebook opens web links in its own in-app browser, rather than using Safari or whatever the user's default browser is.

Presumably this is the only way they can inject JavaScript into websites visited by users?

Apps using in-app browsers for anything other than parts of their own functionality (for example showing a page from their website) without an easy to use "Open in Browser" button are really showing contempt for their users in an attempt to keep people in their App.

I've even seem some webpages opened from ads in Instagram not working and they can't be reloaded
