For the same reason that most of Linux uses GPLv2 without the "or any
later version" clause: because developers didn't want automatic upgrades
to new licenses without the chance to read them or approve of them.

And for that matter, all versions of the OSL have incompatibilities with
the GPL. The sparse FAQ notes that that occurred intentionally, and
motivated the original choice of license.
TTBOMK, newer versions of the OSL seem sufficiently less egregious that
Debian has accepted them. I think Debian primarily objects to clause
10, which newer versions revise.
Sparse's license has come up on the list several times. At least one of
those times, the question of relicensing it came up; it seems that none
of the developers object to it. However, quoting Linus from one of
those discussions:

If anyone wants to try to find the right people to talk to, and for that
matter to get explicit assent from each of the developers, I would
greatly appreciate it.
Sparse's license has in at least one case made it difficult for a
potential user of Sparse, namely the gobject-introspection work.
