As your friendly neighbourhood historian, perhaps you could read this.
The young man in your link is being disingenuous in the first paragraph (or he hasn't done his research/he has copied statements from the left-wing press). He says;
"Speculating on why Obama might have done this, he [Boris Johnson] suggested—with more than a hint of Trumpian Birtherism—that this might have been ‘a symbol of the part-Kenyan President’s ancestral dislike of the British empire—of which Churchill had been such a fervent defender.’
What Boris Johnson actually wrote in the 2016 article;
" Some said it was a snub to Britain. Some said it was a symbol of the part-Kenyan President’s ancestral dislike of the British empire–of which Churchill had been such a fervent defender. Some said that perhaps Churchill was seen as less important than he once was."
In fact, BJ was simply referring to what other people had said/written about Obama, for example:
The Guardian 2008:
"Could Britain's colonial sins pose a risk to our relationship with the soon-to-be most powerful person on Earth?"

Forbes Magazine 2010:
"Is President Obama Anti-British?"
"He has, it is argued, a hatred of British imperialism, which is why, rumor goes, he had a presentation bust of Winston Churchill removed from the White House, Churchill being viewed as a British imperialist archetype."

Telegraph 2011:
"Former Arkansas Gov. Mike Huckabee told a New York radio station on Monday that Mr Obama's youth led him to resent the West, which he said explains why Mr Obama's foreign policy differs so greatly from that of his predecessors."
"One thing that I do know is his having grown up in Kenya, his view of the Brits, for example, (is) very different than the average American," Mr Huckabee said, pointing to Mr Obama's decision in 2009 to return a bust of former Prime Minister Winston Churchill."

How accurate are the 'facts' in the rest of your link?
