> The last thing the Internet needs is even more dependence upon Google.
This doesn't change that? It's a google streaming device that in order to function at all requires a connection to google's data centers.
Why does it matter if that connection happens via 8.8.8.8 or some other IP resolved by a different DNS server? What is the actual, practical difference of that? It's still connecting to Google in order to provide the singular feature of the device. And if you didn't want that, then don't buy the product? It's not exactly surprising that an internet streaming stick requires connecting to the product's cloud services, is it?
If they hardcoded some other google IP and it wasn't a DNS server at all, would that still bother you to the same degree? Would you still be ranting about a "free and open internet"? If not, then your objections in this case are probably misguided to say the least. Because this is really just an implementation detail of the Cast device connecting to the Cast servers. It doesn't change your privacy. It doesn't change the shape of the internet. It doesn't change anything significant. And if you really, desperately care for some reason you can route 8.8.8.8 wherever you want.
Otherwise by blocking 8.8.8.8 you're breaking the free & open nature of the internet. You've done the thing you're ranting against and censored the internet.
