This reddit thread has a nice summary

My stance on Proton is my stance on GrapheneOS: just because the creator is bad doesn’t mean the software is bad. As long as the software is better compared to the alternatives then I seen no reason to stop using it.

Note: better can mean more privacy-friendly, cost-friendly, sustainable, nice to use, open, etc.

Oddly enough, I found the opposite to be true with companies like Nestle: the news of them killing children makes me dislike their chocolates.

On an unrelated note, I wonder if Snowden would come back after a pardon now that he’s a Russian citizen.

Doesn’t Spiral count?
