Ask HN: Is Google's Data Driven Attribution effective, or a money grab?

My wife's small business just got an email from Google that they're switching her ads plan to this Data Driven Attribution thing and I can't tell if it's a good idea based just on what Google says. Given their recent woes, I'm wondering if this is just a cynical effort to get more dollars?
