It's important to distinguish between the different threat models, of
which there are at least three:
1) Sharing of purchased licenses.
2) Generating fake licenses (keygen).
3) Changing the application code to not need a license (crack).
AP is very good against #2, does nothing against #1, and is very poor
against #3.
#2 is a big threat, because banning codes is mostly ineffective
against it due to the limitless supply of codes a keygen can provide,
codes are easy to share, and easy and safe to use.
#3 is, IMO, less significant. Cracks are harder to find and are risky
to apply (who knows what kind of evil stuff that crack does?) so many
fewer people will use them.
You, of course, need to set your own priorities. But saying that AP is
"extremely weak" is misleading. It's weak at some things, strong at
others, and if its strengths line up with your priorities then it's a
fine choice. If they don't line up, then obviously you should look
elsewhere.
