This news ultimately seems like a good step. Regulating print media and larger news outlets has been more central in the past, with established norms in place, but with new media and YouTube, many people haven't been sure how to properly regulate it. Game companies(and many companies outside of gaming) have used this grey area to their advantage to get away with easier base manipulation of people. It's overdue for the FTC to look more at YouTube and Twitch.
Sponsored text-based coverage should have appropriate sponsorship disclosures in the text, and sponsored video-based coverage should have sponsorship disclosures in the video. Hiding sponsorship details in the fine print is obviously deceptive. It's not surprising that YouTubers are taking money for good coverage, as that has been going on for a decent amount of time; the same has been going on at Twitch. The big matter of concern is proper disclosure of those sponsorships, and hopefully this latest ruling will lead to more YouTubers being even clearer about their paid content.
As for the recent CSGO gambling scandal, it's not surprising in the least, and the main guy involved seems committed to continue to lie and deceive people about it. People should keep it in mind with his future videos and perhaps consider just watching any number of other people online.
Some encouraging accountability on these recent issues. Hopefully it means more FTC attention and better sponsorship disclosures in future online gaming videos and streams.
