I've tried YaCy, but the amplitude of the crawling community it's way too little to make it usable so... For now there are not much options, for maps the situation is better with OSM, but still far from being usable like Google Maps for navigation or even only mere exploration since the coverage here and there it's even MUCH superior but for many others is next to void.
To been able to avoid commercial search engines we have only an option: public funding public universities who cure national infra (something already existing, but bigger) and a public indexing project with a national plan for a homeserver per connected home (much like actual ISPs 'router', only pure FLOSS handled by the user or using anyway public code) witch in the other functions also index a small part of the web in an open project like YaCy. Same thing for VoIP comms.

WE DAMN NEED institutionalized FLOSS.
