It’s in the document they link pretty early on. You can argue they could make it more obvious in the blog I guess but that’s flimsy IMO and calling it hidden isn’t accurate

Fair enough. Yes, it is in the linked document. I agree that's sufficient. I was responding to people suggesting that Mozilla didn't need to declare this at all.

All good. I also tuned down my language a little bit there, that came off as a little harsh and lecturing, sorry about that

By your logic it's also better if Ray-Ban and Oakley don't publicly state that UV light is dangerous and that people should use sunglasses if outside.

That sounds silly.

I said that they should have declared the conflict of interest, not that they shouldn't have made the statement.
