Copying my reply to someone else:
What did they interrupt the episode for? Because a number of companies have adopted the policy that, if the interruption is promoting something else offered by the platform - say, a different program, or another tier of service - that those interruptions aren't really ads, because the company isn't actually getting paid to air it. It absolutely looks and acts like an ad to the viewers, but the companies are trying to redefine the word.
Not mine, but the one where Michael Jackson is the love child of Diana Ross and Smokey Robinson caught my attention when someone posted it to reddit.
