Well I don't think there is anything inherently wrong with Google. So suddenly people have started to become suspicious about what data a router is able to collect, while in fact various routers which are well capable of executing malicious applications have been around forever? This is just a trend and Google is not some inherently evil guy that acts outside of the norm. Ditch Google? Fine. The next alternative you find is equally, if not more, likely to perform some data collection. Of course you can go full Stallman and ensure your data are truly guarded by your own in every possible sense. But the heavy price that comes with it, we all have seen.
