This part of the FAQ makes the project interesting:
Services like Google’s Search Console allow website operators to optimize their search page for Google – thus Google crowdsources the robust parsing without making this information available to third parties.
A new search engine is at a disadvantage without that data. Website operators don’t bother maintaining their information at an unknown search engine. Hopefully OWS becomes popular enough that operators use it, e.g. to indicate when their site needs a recrawl or which parts of their site have to be indexed.
There is only one choice: feeling or rationality.
When you feel, you do what feels best.
When you think, you do what is the most valuable.
So no free will but that choice.
