according to an article linked elsewhere (https://www.baynews9.com/fl/tampa/news/2022/05/06/florida-ba...) it was because they had too many black people depicted as athletes and they had word problems that treated scientific facts as if they were scientific facts.
The one example that I thought might have been somewhat improper was "Multiple exercises related to a debate between Al Gore and Rush Limbaugh, where the publisher was in favor of Al Gore's arguments based on the questions in the exercises."
If the debate in question was fictional, I'd be tempted to agree it would have been better to avoid using the names of real people although I'd disagree that is enough to ban the use of the textbooks. If the debate was actual and the textbook pointed out very real flaws with Rush Limbaugh's logic (especially if they were a real world example of bad math) I'd say that it makes perfect sense to include it in a math text book.
