For the meaning of free/open there's a few sources to look at. When it
comes to data there's opendefinition.org, but if you look at free/open 
outside of data  there's the Open Source definition
and the DFSG (http://www.debian.org/social_contract.html#guidelines). 

All of these allow attribution and share-alike requirements. For the 
ODbL, the requirements are

> You must include a notice associated with the Produced Work reasonably 
> calculated to make any Person that uses, views, accesses, interacts with, 
> or is otherwise exposed to the Produced Work aware that Content was 
> obtained from [OpenStreeMap], and that it is available under [the ODbL].

For CC BY and CC BY-SA, our old license, the requirements are

> You must keep intact all copyright notices for the Work and give 
> [OpenStreetMap] credit reasonable to the medium or means You are 
> utilizing by conveying the [pseudonym OpenStreetMap]; the title of the 
> Work if supplied; to the extent reasonably practicable, the Uniform

Many of the companies failing to meet attribution requirements are using
OpenStreetMap data for the majority of their map data, and sometimes have
no attribution at all. The OpenStreetMap requirements are less onerous than
alternative commercial sources, and our attribution requirements are the
same as or less onerous than most open data from governments.
