I bought the Racial Justice bundle and have been playing through the games. I'm up to around 200 played (slowed down a bit now though) and would say that perhaps 1:10 is a keeper. Which, for five bucks, is still a lot of half-decent games if you can find them. I saw a number of games I recognized in this bundle as well so I know there's at least some quality in there. In my opinion/experience, anyway.
This isn't counting all the music/asset bundles and TTRPG one-page homebrews and other non-video game stuff that's in there.
The money itself goes towards the United Nations Relief and Works Agency versus getting mailed to Hamas or some other nonsense. It's humanitarian aid to help alleviate the civilian cost of war regardless of political considerations.
Edit: Also, it has Laza Knitez!! in it which is a $100 game so you can't afford NOT to buy this bundle.
