Probably just some anti-Foundation skiddie who saw this:
https://bitcoinfoundation.org/2014/09/bitcoin-org-walk-down-memory-lane/
So you are saying it is not credible that the site is sponsored by the Foundation but claims it is completely independent ... and now people are mad?
The Foundation is welcome to help bitcoin.org.
As for the worry that the Foundation could try to "buy" some control over the website, I was concerned this could happen when we started having recurring costs (server) until we had alternative funding options. So currently, the sponsorship is just a "win-win" for everyone, and the Foundation thus far is only helpful.
