There are different models claiming free stuff. One is a google-style lock into an ecosystem of free apps that a company can monetize at any time. Stay away if possible: the users will be milked sooner or later. The other is openstreetmap-style set of free data that anyone can download anytime, plus some apps (maybe free, maybe not) using it for some function. I see no problem with it as the lock-in is highly unlikely because the main feature (say, map data) is always available. My 2c.
