You mean for software features and the like? Some good work has been done there in the background – it's not stuff that readers would notice, but contributors do. It wouldn't be fair to say that all the money has been mis-spent – there are lots of people working at the Foundation who are doing good work and who are not getting rich – especially bearing in mind the cost of living in parts of the US (though this begs the question whether the work could not be done more cost-effectively elsewhere).
