I do agree on that and personally don't like to use a privacy protector though it is on my oneplus 6 now.
However, we cannot also deny the fact that some people may still be looking for it just like some may like a full coverage glass but it may not work with their case.
Some may prefer a non full coverage one instead.
I think that everyone has different opinions and what is nectar to one, may be poison to the other.
