While some French publishers, have not understood that pay 6 times more for a product (even by including translation costs) is somewhat exaggerated;), and it begins to know, they will go - in the final - to bankruptcy, because you can not fool "everybody", "all the time".
The reader, whatever the interest for an author, a series, or will turn to sources less 'disreputable' or read library rather than buying, or - even worse (worse than being hacked, threat to be ignored) - disdain that it will take to a scam artist (rightly or wrongly) and will redirect to the publishers more attentive to its customers / readers.
