Two comments:

(1) The sticker claims that the textbook does not address certain issues. But those ‘issues’ all stem from simple misconceptions about evolution and science in general and are easy to address. Perhaps biology textbooks should address them.

(2) What proportion of students in any school are in the habit of reading parts of the textbook on which they are not going to be tested? A very small proportion. And of that small proportion, surely the vast majority are students who are actually interested in the subject and are therefore not going to fall for such double talk. So the sticker is essentially nothing more than a harmless source of amusement to its readers.
