bitcoin.org is owned by bitcoin developers.
bitcoin.com is owned by person/people who provide bitcoin services.
But who owns the "Bitcoin" brand?
bitcoin.com is actually anti current bitcoin btc technology. they forked off to bch - bitcoin cash, and they are trying to push it as the real bitcoin. obviously with their hashrate and usage, it is laughable. also they have r/btc on reddit. real bitcoin group is r/bitcoin.
just fyi
