Ugh. By your logic Firefox also should be ostracized, because Mozilla also using some of the money that Google makes thanks to their dark patterns.
But indeed, the funding from Google is a big issue for me. I hope they eventually manage to get rid of it. It's not sustainable, and also one can't be 100% free to say fuck the Google's business model while relying on Firefox. I also suspect this funding may be preventing Firefox from being as good as possible with respect to privacy, to avoid upsetting Google. I would not be surprised there is something related in the contract between Google and Mozilla.
More generally, all the 3 current mainstream browser engines depend on GAFAM funding and I don't like it.
I'm looking at emerging alternatives with great interest. I see new developments on Servo and Ladybird with a good eye.
