Ok, see the contradiction :
You : monopolist ... Microsoft used to be
You again : monopolist (which Microsoft is
Having a de-facto monopoly doesn't mean you are compelled to write or even help write applications of any kind
Ok, so Google is not compelled to write Youtube application. They are going by your logic exactly, you should be happy.
What it does though is ban you from putting obstacles in the way of a competitor
Microsoft's refusal to help me write MS office for my Linux tablet has put obstacles in my path, even with such an advocate with such good offices with Microsoft as you have, where I am a potential competitor.
Nobody (not even Microsoft) is asking Google to help them do anything

they are asking Google to not put roadblocks in the way
Like my 9 year old son, Google is being cautious with Microsoft after Microsoft showed it is not to be trusted. You should be happy about it.
