Somehow because Meta has released a popular OSS library and dedicated over 10 years of engineering resources to it (that has generated immense value for the wider ecosystem), that they should've shelled out more than the $3M they're contributing in order to give its ownership away to a non-profit.
Maybe it's just me but I think they've contributed more than enough. I'm grateful for what they've already contributed and anything else they choose to contribute in future.
