could embrace it in a weird way

only open source the framework for the server and client

then companies / communities / etc, can make their own algos, and buy their own servers. The reward for proving your servers / crawlers is more people use your algo (higher chance of hitting your nodes)

and then allow the client to have configurable automatic node filtering, along with manual node filtering, so if a person feels that a specific node set is just full of bs, they can filter them out (and also prefer certain node sets in turn, to which they can donate if they are consistently happy with the results)

its like, choose your own filter bubble.
