AFL protection - Protectionism vs Free distribution

We have seen many examples. Linix is a freely distributed 
OS, and much of its growth is attributed free distribution of source 
code. Linix's core developers didn't have the budget or man power to 
grow its market without tapping into the overall community for 
free contributions. Microsoft on the other hand, strongly believes 
in its inhouse developed edge and tried to guard it as much as 
possible, by keeping it as secret as the laws allow it. 

Open source is always the fastest way to spread the use of a 
software product. Take a look in the AFL library, I would argue that 
most afls posted are small, rudimentary and often specific their its 
purposes, their utility relies on the fact that they can be easily 
customised, and the open source serves as documentation on what 
needs to be done. They are completely open to the adopters 
imagination. When AFL becomes encrypted, or protected, they 
become canned, and has to be used as it is. For any canned product 
to be out in the public, regardless whether it is free of charge or 
not, it has to cater to all or most of its users need, and not just 
the writers. There is a huge effort on the writers part to analyse 
the needs of the type of users that he wants to target. They called 
that system analysis in software development. Then he has to develop 
it, and then carry out all sort of tests, more than ever. Because 
now protected, no users can contributed to any debugging whatever. 
After all that is done, the writer has to thoroughly document with 
user guide, reference guide, etc. Because no one will know how to 
use it otherwise. With the exception of the few who are selling 
their ware, most will not want to go through that trouble and shy 
away from contributing. By the way, any encrypted afl will be 
cracked within day, if not hours. We have encrypted vbscript and 
jscript today, they are neither secured or popular. 

If answering a few question for curious users on how to modify 
author's code is tieing up the author's time. Then canning AFL is a 
sure way to killing all his time!

If someone really wants to protect their intellectual property and 
has deemed it worth protecting, they should convert their ideas into 
dlls or have them converted by someone. Dll fullfills the needs of 
protection totally and is far more secured. without forcing a new 
barrier onto the masses.

In my view, afl protectionsim is aiming at guarding the fortune of 
the few, because there will be very few who will wants to use it. 
the majority will be just happy to share the ideas, no matter how 
small, freely and easily, or not at all.

If AFl protectionism becomes reality, Tim will soon be asking Why 
are there so few AFLs. LOL! In another twisted way, I have answered 
once more why there are so few dll.
