Here's a small thought experiment.  Suppose I were to make all of the data
that I have submitted to OSM also available under a CC-BY (not SA) license
(I am not saying that I will do this, but I might do if it made sense).  Any
data in the OSM database that was initially created by me, from tracklogs
that were also created by me, and not subsequently edited by someone else
would effectively be available under that license.

Obviously, if I edit data created by someone else, or if I create data based
on someone elses GPS tracks then those nodes and segments would be SA.
Likewise, if someone else edits my data then the edited data is now SA.

Since 99% of the data in my area was contributed by me and AFAIK there have
been very few edits by others, I'd guess that 95% of the data could be
extracted and used with whatever license I choose to allow.

If more and more people were to unilaterally consent to make their data
available under a less restrictive license then the polluting effects of the
SA license would become less and less, until it becomes almost irrelevant.

None of us are lawyers here, but most of us have technical skills.  We don't
have the skills to solve this problem by making new types of copyright
license, so lets try to solve the problem using technology.

Who here would be prepared to unilaterally relicense their data under CC-BY
(not SA)?
