Exactly.

Dear John, as has already been told you by Tobias and Mihai, the key
difference between the GNU GPL v2 and the APSL v1.2 (here) is that
the GPL only requires to make source code available to recipients of
object code, while the APSL requires to make source code *publicly*
available, if you just send modified object code of one friend (which
is a third party) or even if you just use modified object code
internally within your business or organization (for anything that is
not R&D or personal use).

Moreover, the APSL always requires you to continue making source code
*publicly* available for at least 12 months, while the written offer is
only *one* of the options to comply with the GPL: the other option is
offering source code along with object code and never having to worry
again about the thing.

I agree with Tobias here.
Quoting the [APSL v1.2]:

[...]
| 1.4  "Deploy" means
[...]
| as well as
[...]
| distribution of Covered Code by You to any third party in any form
| or manner.
[...]

[APSL v1.2]: <https://opensource.apple.com/source/hfs/hfs-522.0.9/APPLE_LICENSE>

This would be a good outcome.
I really hope Apple may be persuaded to re-license hfsprogs under the
terms of the [Apache License v2.0].

[Apache License v2.0]: <https://www.apache.org/licenses/LICENSE-2.0.txt>
