This is just a theory but please hear me out.
Remember when the DBZ wasn't done by FUNimation and we had all those edited 1st and 2nd seasons from Saban and every hardcore fan was pissed?
Then years later when FUNi released DBZ's first 2 seasons uncensored, every viewer was slightly more pleased.
Well, it was said in Season One; First Voyage and then again in Season Three, First Voyage's commentaries by Colleen Clinkenbeard and Mike McFarland that FUNi was actually looking at One Piece back before 4Kids had it but failed to get it. The two went on to say that after 4Kids surrendered OP over to them all the studio has been hearing is positive feedback from the fans.
Now take what they said and perhaps there was a conspiracy if Gen Fukunga head of FUNimation came up with the idea all along to let 4Kids take and run One Piece into the ground to the point that fans would beg FUNi to save the OP like they did with DBZ. That way the fans who had to put up with the crap version would accept any improvement and sales would go through the roof.
Just a thought, but then again we are talking about the company that decided DBZ's original score wasn't good enough. So maybe it's just my imagination. What do you people think?
