25% is pretty close for 10.6-10.8 combined. However, the current

I'm not sure the difference between "abandoning" and "irreversibly
locking into being abandoned in ~1 year" is all that great. After
initial drop-off, these versions have a pretty stable tail on them.

OS X 10.7, in particular, was the first release to leave behind the Core
Duo and Core Solo Intel hardware, which is still pretty capable and
(apparently) still used by some sizable portion of the Mac community
[1]. You'll notice, for example, that 10.6 has many more users than 10.7
or 10.8 does; and, in fact, appears to still account for 1 out of every
10 Mac users.
To be clear: these users _cannot_ upgrade to 10.9 or later. It simply
won't install.
To put this in perspective: we continue to support XP, some 9 years
after after the January 2007 release date of its successor. OS X 10.9
didn't come out until October of 2013, which is only two and a half
years ago.
