I would not be so sure about this. The Intel Audio/Video chip in the O2 (which I believe was custom designed for Magnavox) is more complex then the TIA in the 2600 since it handles all the video display logic internally plus it has a built in 512 bytes of character set data. Intel may have been able to develop and manufacture these chips cheaper the Atari because they had a little more experience in chip development then Atari did at that time.

I wonder exactly when the O2 was released. I am pretty sure the 2600 came out at the end of 1977 for Christmas, if the O2 came out early in 1978 then thier R&D may have been completely parallel and one company may not have had much info on what the other was developing.

PS. I am not trying to advocate 1 system over the other, It's just interesting to compare the technology.
