I'm with Ralf, a petition isn't going to do anything - it may get their attention, but they won't do anything about it.
And Wildstar, the problem is with educational programs like this, early childhood development continues to improve year after year, and as such, their methods to teach have to change and evolve to not only keep up with the times, but further educate kids beyond skills they may have already picked up on. Sesame Street has the same problem, people made a big deal out of the Old School DVDs with episodes from the 1970s when they came out because they contained disclaimers that said, "These early SESAME STREET episodes are intended for grown-up and may not meet the educational needs of today's preschool children." that was back when they mostly taught letters and numbers among other things... fast forward to today, they're actually teaching engineering to kids now.
Aside from that, I still have a feeling a lot of it has to do with continuity... you have to admit, the characters were different in the earlier episodes, like Binky being a bully (moreso than now) in the first season, among other things, they probably don't want to confuse the kids watching as to why Binky's a bully all the kids avoid one day, then one of the gang the next.
