What makes you assume YC has no ethical basis for investment?
Also, there's a big difference between using a free product and working for a company that supports China/Saudi Arabia/etc. Or in YC's case, bringing billions of dollars worth of investment into a country that sends Muslims to concentration camps, and helping them build a dystopian surveillance state that will force everyone to spread their propaganda and fall in line; while being completely helpless as hundreds of millions of lives are destroyed..
That being said, I do try to avoid using products of unethical companies, and I would resign without a second's hesitation if I found out my company was involved with these evil governments.
Not really a big fan of China, but lets be a bit more consistent here.
China is in the middle of an empire-building enterprise and like every such enterprise, (UK, Russia, United States), does many awful things. Yet compared to some places in the Middle East, I don't think it's nearly as evil. Certainly not "the greatest evil the world is facing today", (the only way I can see that is if you think U.S. global supremacy is great).
Personally, I'd argue the greatest evil the world is facing today is people in power ignoring climate change.
> only China is capable of forcing almost every country and company into their submission
You must have missed the war in Yemen, as an example.
> there's a big difference between using a free product and working for a company that supports China/Saudi Arabia/etc.
How so? The products I mentioned are not free software for the most part, by using the product, (even their "free" plan), you're supporting the company China/Saudi Arabia invests in and thus supporting these governments economically.
> bringing billions of dollars worth of investment into a country that sends Muslims to concentration camps
As I said, that's really a case against empire building and a case I agree with, however it's been done by every empire. Similar things have happened at black sites in Iraq etc. so I think the consistent line to take is to be against investing in any empire in that case, which would include YC's home turf.
> I would resign without a second's hesitation if I found out my company was involved with these evil governments
That is a great stance, however the cynic in me thinks they probably already are in some way, even if you don't know it.
