There are 2 different "PR" campaigns that happened.
The first is Open Source vs Free Software. There's nothing shadowy about it. It's right there in the open. You can see who finances OSI. You can read what have to say about making Open Source business friendly and branding a new term vs "Free Software".
And you can see how shortly after they started promoting the term it took off in popularity. They didn't invent the term, but they definitely popularized it.
The 2nd PR campaign is OSI convincing devs that only software that only software that uses an official blessed license is pure.
