Oh dear. Where to start.
No action of a parent can remove US citizenship from a US-born child. To renounce your US citizenship is a cumbersome process and must be performed by an adult. Obama's adoption and acquiring of Indonesian citizenship is not recognized by US law.
The US does not recognize dual citizenship. It's neither prohibited or encouraged, it's just ignored. As far as our laws go, holding citizenship in one or more other countries does not affect one's status as a US citizen in any way.
Were this otherwise, Libya or Sri Lanka could grant citizenship to any US presidential candidate and therefore make him ineligible, obviously not something we wish to allow.
Obama’s adoption and acquiring of Indonesian citizenship is not recognized by US law.

Interesting statement. No proof. Just a spin control statement.
