Bascom AVR is popular in places like Iran
Those Google trends go to nowhere.
From this trend:

I can quickly draw the conclusion that Arduino IDE is of interest only in California and New York. The interest is zero in the rest of US.
The interest in AVR Studio is high in at least ten US states including California and New York.
The interest in Arduino IDE is high in Japan, Italy, Germany, California and New York and zero in rest.

Maybe there are distributors there, stores from where you can buy directly Arduino boards and having a board you are obliged to use Arduino IDE.
