ABIW, the point, at least from my POV, is that the misuse of the apostrophe, other punctuation and spelling is a jar to the senses of those with sensibility, and it destroys their understanding of the text. By the time they had deduced the probably intent of the author they will probably have lost patience and lost the gist of the whole message.
The recent DIN that misused PERSONAL when it meant PERSONNEL in relation to the use of image capture devices was a case in point. Not only that but legally the instruction becomes nonsense.
The whole point of correct spelling etc is to ensure accuracy of content and understanding of intent.
