I really liked your article, but though you mentioned Google (though I disagree with your conclusion that they accept and act on imput from their customers, I would prefer to qualify it to: listens to some of their customers - those who agree with their own politics), what is missing for me to give you an A+ is the lack of mention of names of companies who deserve our support.
I am hoping you and other readers who have the information, will create a list in this comments section.
I mentioned Google because they are at least being transparent. That is a huge step down the road of trust. They are listening to their employees and to customers. They took the bold step of creating an externally populated oversight committee. That is huge. It also bit them in the backside, but they are being bold. So I have to give them credit for that.
As for a list, you can look at recent reports, take a look at https://ai4good.org/ and their upcoming conference where they will be listing some of the leading AI/Ethical companies. But in my opinion, we are way too early to dole out grades. This will take time to temper. The real differentiation is publishing a formal AI/Ethics position and being transparent to see if it is followed. Baby steps.
