who said they need to use reactOS or "replace their foundation", which is a term i cannot parse, i don't think anyone wants to use this as a server platform (that was my default assumption of that phrase.)
this is "we have a market cap of 61,271,506 times the median household income in the USA, we can afford to peel off 1/500,000th (0.0002%) of our market cap per year to make this project awesome because we like this project and want to see it grow"
Well if that's the case, then what you're arguing for is charity. That's fine, but the upthread topic has been about business case. If we're looking at it as charity and not a business investment, then it's a much different conversation. I'd certainly love if companies did things like this and would highly applaud it.
