I'm not so sure about that.

Of course I'm aware of keyfiles given for free and also of keyfiles not paid via PayPal but in person at several events where MorphOS Team members were attending. What I'm not aware of however is that such keys are bound to registration numbers in the MorphOS registration system, which is directly linked to the PayPal system. So, can you say for sure that keyfiles received for free (such as the ones you got) get such numbers in the MorphOS registration system? If yes, this may be the case with keyfiles paid for in person as well, which in turn would show up as non-paid for in the PayPal system but represents a valid license issued.
Nonetheless, I'm quite sure there are registration numbers occupied by people who attempted to register and got their number in the email with the payment request, but then for whatever reason have not made the final step to perform the actual payment.

Even if keyfiles issued for free get their own registration number, this cannot account for *all* numbers shown as non-paid for in the registration system (see above).

Exactly.

Yes, the portion of those is up to anyone's guess.

True. In case the free keyfiles and the keyfiles paid for in person are indeed included in what we treat as the MorphOS license counter here, we just know for sure that the actual number of keyfiles issued must be lower than that.

As has been explained a number of times in this thread, even the MorphOS Team can't know this number.

> I guess we will not be able to determine either number

Agreed.

> many MorphOS users who would rather this new information had not come to light

This is not new information in any way. It has been clear since MorphOS 2.0 and also discussed in this thread that registration numbers can be generated without keyfile subsequently being issued, simply by not following through the payment.
