From the article:

Several researchers MIT Technology Review spoke with condemned the effort to commercialize geoengineering at this early stage. Some potential investors and customers who have reviewed the company’s proposals say that it’s not a serious scientific effort or a credible business but more of an attention grab designed to stir up controversy in the field. 

Luke Iseman, the cofounder and CEO of Make Sunsets, acknowledges that the effort is part entrepreneurial and part provocation, an act of geoengineering activism.
