If it's an empirical fact, how much objection from how many (and which) people is enough to cross the line into controversial? You can always find at least one upset person about any significant decision of any company, thus it's inherently political when you decide which group of people or how big a group you have to have to merit the "controversial" badge.
Those complaining of being deplatformed would probably agree strongly with your definition, however, so I will admit the definition of this word is itself controversial. Or maybe I shouldn't, because the prior sentence feels very political to me.
