I think they removed petit solely because this was eventually coming out and they didnt want people to buy the old one while waiting for the new one and not get the new one.

Sorry but romoving the old one in FEBUARY before the new one comes out in OCTOBER is just not cool, bruh.

Besides a pretty sure everyone would want to upgrade to smile basic once it comes out . additional features :P.

I'm glad I moved Petit Computer to my 3DS when I could. This version is even better, of course, but I still have some PTC projects that I use regularly.

I think the main reason PTC was removed was because SmileBOOM had it published through Gamebridge. Their deal with Gamebridge eventually ran out, of course, and PTC apparently wasn't making enough money to make the deal worthwhile, so it expired and PTC had to be removed from the eShop/DSi Shop.
