The ARM Chromebook costs less than x86 Chromebooks while offering more-or-less the same user experience and it's much more popular in sales, according to Amazon.
So, Intel is/was a part of the problem at least for Chromebooks. (I don't know anything about Google TV)
With that said, Intel has been way too slow in its race against ARM, but saying that this has impacted Google I don't find credible.
