Realistically, either you ignore the privacy concerns and set up routing to multiple providers preferring the fastest, or you go all-in on privacy and route DNS over Tor over bridge.
Although, perhaps, having an external VPS with a dns proxy could be a good middle ground?
If you're the technical type you can run Unbound locally (even on Windows) and let it forward queries with DoT. No need for neither Tor nor running your own external resolver.
And it’s not conspiracy theory - it was very suspicious when we did some testing on small, aware group. The traffic didn’t look like being handled anonymously at Google side
Yeah it's not like they have a long track record of being caught red-handed stepping all over privacy regulations and snarfing up user activity data across their entire range of free products...
