I believe Charlie Lee used Scrypt because of Tenebrix's claims of its resistance to GPU, FPGA, and ASICs? How was it Charlie Lee's fault that Scrypt was not resistant to the development, and creation of specialized hardware for it?

Scrypt has setting that decide how much resources are required.
The Scypt setting used in Litcoin were too low and allowed it to fit in a GPU.
Charlie was GPU mining long before the GPU code was released.
I posted about this before Litecoin started in the Tenebrix thread:

There are other comments there about it.

Proof of Work
We really liked Tenebrix's Scrypt proof of work.
