I'm aware of this policy. I cannot re-find the source, but there was an investigative piece somewhere that found they continued to take money from fossil-fuel aligned companies. I cannot find it after trying to look again admittably, though I am unsure if it because of my poor memory and that it didn't exist in the first place or because search engines are poor at this sort of thing. They do however continue to take ads from very high carbon industries like airlines and the such however.

They largely share my views, I am not suspicious because they don't align with my views, I am suspicious of all profit-motivated companies equally.
