So many companies have a very short list of "approved" compatible devices and get ornery if you use something else; often those approved devices are unavailable under that exact product name or number and so you're left guessing as you replace stuff in two, three, or four years, which is actually when you're likely to find yourself needing to replace components like this. The very worst companies (ahem, Apple) only validate their own devices for inter-operation with their products, and act as though using something else would be the pinnacle of recklessness. Some even threaten it'll void the warranty (which is actually not legal in many cases, but companies do it anyway).
The fact that someone from Google is doing this in a non-Google location for the benefit of the standard and of their customers is just really nice. Certainly, it is in their best interest to have their devices behave reliably and not be damaged by shoddy third party devices; and so Google does benefit. And, yet, many companies just don't see it that way and are willing to screw over their customers just to get that extra few bucks after the sale for accessories that could just as readily be provided by third parties (and often third parties offer more variety, making them more fit for purpose in some cases).
In short, I've lost a lot of trust for Google over the years (mostly as marketing and violation of privacy became their primary revenue sources), but this is a good thing, for the consumer, for the industry (standards are great! implementing standards poorly is bad!), and for Google.
