Why people don't like privacy screen protectors?

I used a lot of screen protectors and didn't like the grainy low quality look of the paperlikes nor did i like the normal look of the tempered screen protectors but for the last week I've been using a privacy screen protector and it makes a pixalated transverse scanlines effect which i absolutely adore and i just can't take away from looking at my phone or to read things it also made it so that reading stuff is easier on my eyes too just want to know why people don't really like the effect it gives cause i certainly dig and love it!

If any of you guys love crt look or scanline look def go for a privacy screen protector it just looks amazing

Device is poco x3 nfc btw i still rock the good old phone
