He explained... MinecraftForge wasn't continued and Tekkit basis was this mod. So if MinecraftForge doesn't upgrade, Tekkit Classic doesn't too.

For example :

We have a type of salad, the TekkiSalad.

It is salad made of green lettuce, tomatoes and nuts.

There is a problem in the orchard and the green lettuce ( MinecraftForge ) rots. We do a new salad, called LiteSalad.

We substitute the green lettuce for red lettuce ( BukkitForge ). The tomatoes (other mods like IndustrialCraft) still in the salad. But there is also another problem, nuts (some mods) were accompanied by the green lettuce ( MinecraftForge), so they can't be in the LiteSalad. We substitute the nuts (some mods) with asparagus ( new mods, like Treecapitator, Thermal Expansion, Steve's carts) but if previously there were 4 nuts, now we put 20 asparagus. So we get a new salad, with new flavor and new complements, and we get the LiteSalad.

I hope you understood the example :P
