These huge companies lie to their teeth even though they have legally sworn they will not do what they shouldn't do. Big companies will always find loopholes, legally or not, to have things their way and to make more profit off of their consumers without them knowing of what these huge companies are doing. IMO, $150m is not enough of a fine for selling users data. It should be more. Remember Google's $5b fine in EU? Not entirely similar case but the nature through which they took advantage of their users is very similar.
is it possible for twitter to sell user data to third parties to achieve its career. I'm a little confused by this case where Twitter gets a lot of trust from users but still dares to violate user privacy by selling user data at will. Is there no party responsible for this incident so that users get comfort for the security of their data.
