Well, two points to that: 1) If this person doesn't use Google products, then they are going out of their way to avoid Google. They are then very aware that their values are overruling technical benefits. 2) Surely if they are this invested in Firefox then they know who's been funding Firefox for years?

I'm typing this from within Firefox, which I switched to over the adblocking changes. But I'd say that claiming Google has contributed nothing to society is silly.

There's also the AI stuff with transformers, running the deepmind work with alphafold, alphago, alphazero. And GSOC.

And the papers on bigtable, spanner, mapreduce, etc… bootstrapping modern big data, spawning many opensource copycats.

And Android? I used a linux based Nokia N900 before Android, but clearly the world preferred Android.

Hell, Google Search itself was once a paradigm shifting improvement over alternatives.
