So by your logic simply owning a Wi-Fi access-point at home and not adding strong cryptography is reason enough for a corporation to drive their car to your house and capture your data?

So to keep Google away from logging my network data I need a strong virtual fence now, otherwise they'll come spying on my traffic?

That is 100% wrong. Google shouldn't be snooping on my data at all, not even if my AP was within their corporate headquarters reach. That is simply not acceptable behavior from a major corporation.
