Gates made his money off monopolizing technology. You can find memos where he specifically leveraged his contacts with manufacturers to ignore specifications (which Microsoft helped specify) so FOSS like Linux wouldn't work properly.

I truly believe in a world without Microsoft that todays software would be much safer, private and advanced by quite a few years.

Gates only became a philanthropist after he married, there's probably a very good reason she left, even excluding the Epstein connections.
