Okay, I often wondered if the engaged in that practice of changing their own headlines on articles to get more hits.

You will find multiple links that show the original headline.
Here are just a few:

Interestingly when you look at the search results for the original headline I posted from the NYT you will find a link to the NYT included in the search results but when you go to the link you will find the changed headline.
I stuck to the FR rule to only post the original headline.
It was the NYT that altered their own headline.
