superfluous possessive's

I do not claim to be a grammatical master. Nor do I think that I am the mac-daddy at placing punctuation marks in their proper context. However, I do know a little about the use of apostrophe's and I am bothered by their misuse. I recently found out (thank you d.a.d.) that the use of apostrophe's does not, for the most part, follow a consensus rule across time, geography, or demographic's. But regardless of what the world as a whole thinks, I am here today to convince you that possessive's and contraction's should use apostrophe's while plural's should not.
Sometimes I read. I read to enjoy. I read to understand. And I understand thanks to the guide of symbol's – quotation's, comma's, apostrophe's, etc – that the author employ's to tell his/her story. Through this code, I am able to come as close as possible to the true meaning of the written work. When a writer misuse's a symbol – for instance, an apostrophe – I find myself stumbling over the true meaning of what is being stated.
Let me give you some examples of good and bad uses of apostrophe's:
I am currently reading a book by Tim O’Brien; this author uses apostrophe's like a rock star. On page 10 of ‘The Things They Carried’, he writes: “…and crawl in headfirst with a flashlight and Lieutenant Cross’s .45 caliber pistol.” Obviously, the .45 belongs to Cross. And I know this because of the possessive use of an apostrophe.
Now, let’s look at the photo above. The cookie-packaging editor's correctly made Nana’s possessive. But what about No’s? Does something belong to No? Is No’s short for ‘No is’? I am confused!!! My only reasoning for the superfluous apostrophe is that the editor's at Nanas were on a sugar high from all the non-refined sugars they consumed and became seriously apostrophe-happy. Maybe they thought that their consumer's would think they were eating nitrous oxide (nos) if they left an apostrophe out. Or that they forgot the e in nose. Who know's?
I do realize I am going out on a limb here…because maybe this apostrophe should be there for some unknown reason that I can’t find through a google search. But even if it is, its misuse has confused the hell out of me. So please, practice modesty with your apostrophe use. And in doing so, you won't have to read anal blog posts such as this.
