I personally don't think the Kochs nor Soros are bad people, and likely want what they view as what is best for society. They put their money where their mouths are, nothing nefarious about that. If the Kochs were only for their own self interests their main focus right now wouldn't be criminal justice reform.
Don't be easily fooled by their "generosity" as it's not always as it seems to be, many times they fund "independent" organizations or think tanks which really are just foils for them to push their Conservative agenda.

I can keep going on, so please don't paint them as just some "nice" guys who give money.
Anyhow, you just cited 4 left leaning sites, so that's not helpful (and actually proves my point in other parts of this thread!) Charles Koch himself does not deny climate change (you can read about this in actual news sites like the Washington Post,) he is against corporate welfare like the government directly/indirectly subsidizing Tesla, etc. Which is perfectly in line with his libertarianism.
Even the one source you could argue is somewhat "real," was from an opinion writer. Here's the rest of his pieces, which uh, don't seem so unbiased. https://slate.com/author/mark-joseph-stern
They very much don't put their money where there mouths are, as they put their money through a massive chain of anonymous shell organizations to hide their involvement. This has given the appearance of many right wing "grassroots" movements appearing as by the people, though when donations have been investigated they are overwhelmingly from single donors traced back to the Kochs.
I don't really know that much about Soros, but the fact that people try to claim Soros is just the lefts version of the Kochs is very wrong on many levels. The most basic level is simply net worth, which is their influence ability. Soros is worth 8/9 billion, the Koch brothers are over 100 Billion. Their ability to buy politicians is that much greater.
I believe the Kochs believe they are doing what they think is right, but I also believe they are evil for the country. Their ideals are not what benefits the country in the long run, but continues this trend of money and influence being contained within a tiny minority.
The Kochs are very calculated people, they know what they are doing, and just being they are focused on criminal justice reform, doesn't mean they aren't also focused on other things that benefit them (and that criminal justice reform how they see it doesn't benefit them). The for profit prison industry owners are some of their peers who donate to their causes, they are playing every side they can.
