This quote says nothing about product, but about continuing research. Most researchers don't care about products. Many don't even care about any practicality (just the scientific pursuit). How do I know? Well, I happen to work as Research Scientist. I worked at Google 5y. :) For the majority of my colleagues, "having to" support their work after it was published was a nuisance and they wanted to work on new cool stuff instead.
