Just a show of voters, if you were offered the choice of purchasing an encoded version of an add-on (Ioncube, for example), for a reduced price of the original (say 30%-70%), would you be more likely to purchase the add-on?
For a few people, having access to the source would not be a big worry, and the lower price may swing them in favour of purchasing.
Would you never purchase an encoded add-on? Would it make no difference as to whether you would purchase the add-on? Is price not a factor at all?
