wolsne...they don't even hold the copyright to their own brand.
they dont own the trademark for esea, that's different to the copyright of their tagline and brand image, which was featured prominently in the ad.

this ad looks 100% like an esea ad and uses their tagline. esea's complaint was that the ad broke google's rules, specifically on misrepresentation and destination requirements.
esea were more than fair on this: they offered him $5k plus the cost of the advertisement, and let him keep the original $3.5k he took out. they didn't try to retroactively apply the rules they added on using third party advertisements to get referrals. it's true that esea would probably have gotten most of these subscribers anyway, and the guy basically wants free money (money that he arguably was promised, but he essentially gamed the system to get).
the amount of blind downvotes in the reddit thread shows how much people hate esea though
