Why do Pearl Jam songs leak?

4 songs of the new album LIGHTNING BOLT (which will be released this year the 14/15 of october) have leaked.
I was wondering what the motivation for this was.
Possible answers: DISRESPECT and IMPATIENCE.
The songs have been stolen...
and everybody, including me, wants to hear them as soon as possible...
But one could also say it was/is CURIOSITY and SOCIAL INTEREST...
Everybody wants to hear the new songs...
Somebody put it on the internet so that others could hear it...
Pearl Jam did not want them to be out now... In relation to them there is DISRESPECT. An attitude of "Give me what I want, and give it to me now!"
