What's follow the money mean here? Like Google won't do work cause there is too much cost? This usage of the phrase don't match my understanding (which is the Lester Fremon (The Wire) usage) - in that it leads to corruption.
I think the notion they're trying to convey is Google doesn't have much motivation to make this feature good / humane as it has little immediate impact to their bottom line, compared to a company whose revenue derives directly from how well said feature performs.
