This is a bad take because it comes from linguistic ignorance. The "great" here doesn't mean the person is wonderful with a kind soul and a benevolent impact. It's not "great" as an extra intense "good".

It's great like a Great White Shark is great. Great like Great Britain is great. Large, impactful, encompassing. A person is said to be a "Great Person" if they are seen to have a disproportionately large impact on the course of history. It is this premise, of some individuals being able to have such disproportionate impacts (rather than everything being a product of the times) that certain philosophers and historians have objected to. It wasn't out of concern that we might be glorifying nasty people with the term; if that were it then we could simply change the terminology to "Impactful People" or something like that. Those who've lodged serious objections to the premise of great people would not be placated by this change in words.
