GOOGLE Stands by Tribute ... HARRIRT TUBMAN WASN"T REMOVED OVER BACKLASH

Nick Cannon got fired up about Google's Black History Month tribute featuring Harriet Tubman -- and sparked some outrage on the Internet -- but the company doesn't think it did anything wrong ... TMZ has learned.
If you missed it, Google's homepage on February 1st featured a doodle of the Civil War era abolitionist carrying a lantern. If you slept through your education -- Tubman led hundreds of slaves to freedom through the Underground Railroad.
The image of HT, wearing a do-rag, rubbed Nick the wrong way -- he Instagrammed ... "Really Google? This is the way we are kicking off Black History Month #WhoApprovedThis"
Tubman Tribute Racist?
Our Google sources tell us they did NOT take down the doodle early due to the moderate backlash generated in part by Cannon's IG. We're told Harriet was up for a full 24-hours ... just like all the other Google doodle tributes.
Question is: why was anyone pissed in the first place? There are plenty of actual photos of Tubman wearing a do-rag.
So, we gotta ask what you think ...
