They cover A B testing part in the video.

It's not A B testing.

They also cover the marketing disconnect from the game devs.

It's not really a "marketing disconnect"

I’m not sure how you came to the conclusion that the video misread it.

Because I have been involved in the industry and know what these ads are for. The video is blaming things like trying to swindle people into downloading a different game, false advertising, misdirection, and is blatantly calling it "lying" in the title. That it's trying to pit people into mini games to get them hooked on the outer game. That's not what these ads are for. At all.

He's claiming they know what people want but don't want to build it.... But they are building it?

I came to this conclusion because the video is just blatantly wrong.

These ads are made to test popularity of game ideas before they bother to build the whole thing as a standalone game. He's reading into what he's seeing. I have worked with these companies and know their exact reasoning and it's not what he's claiming. He's just wrong.

I like Upper Echelon, but this take is just misinformed and wrong.
