The academic path is tempting for many. The myth is that you get to spend all day in research and working with ideas. The truth is, a huge amount of time is spent writing grants and funding proposals. It's a whole industry and researchers and scientists at well-known institutions are expected to bring in a steady stream of funding, including funding their own positions. Historically that has been through foundations and government sources (which are massive). It's entirely unsurprising that brands have gotten involved.
