John Lennon and the FBI

I got the new John Lennon acoustic album. I’m still digesting it. I really like “Working Class Hero” and (of course) “Imagine.”
On the back of it I noticed the FBI Anti-Piracy Warning stamp on it. (Apparently this stamp is on all new albums now). I thought to myself how ironic it is that the FBI is trying to protect John Lennon now, when they were keeping a file on him. But, in a sense they’re not protecting John Lennon, they’re just protecting the large corporation known as Capital Records from loosing money on music pirates.
Here is a quote from John Lennon:

“Music is everybody’s possession. It’s only publishers who think that people own it.”

I’m guessing John Lennon would not been opposed to file sharing, or tape trading.
