Thanks for this, it made me go back and read through a second time. Just to explain my confusion, the article states that the price went up from $9.99 to $13.99 earlier this year, however, users that were subscribed through Google Play Music or YouTube Red were able to keep getting the old price for a little while longer. Then the article mentions “$9.99 – or even $7.99 – grandfathered users will now pay $13.99/month for YouTube Premium starting in January.”

Somehow, my brain interpreted this all to mean that there was a $7.99 to $9.99 increase in July. I think maybe I was thinking that because it’s odd to have an article about an old price increase. But really, the article is about the end of the grandfather period for Play Music and YouTube Red subscribers. All other users already had the price increase.
