Does any of this really matter? English is mainly derived from Anglo-Saxon, with infusions from Latin, Norse languages and Norman French (and a few other languages too, I imagine). There are some guidelines, but it's never had an official regulator.
There was no standard spelling until Johnson's Dictionary of The English Language appeared in the mid-C18th and that was premised on London usage. It largely ignored regional and dialect use and vocabulary; and many of these forms are still in common use today. The use of apostrophes has changed over the years too, and I don't suppose most people are even aware of their origins. There's nothing special or sacrosanct about them.
US English is based on UK English during the early period of settlement, with modern vocabulary added where necessary. It's not right, or wrong, it's just different.
Texting and email have changed the use of English too, but it's just part of an ongoing process. I can live with it, providing I can understand what someone is saying without having to puzzle it out. I admit that I do get a bit irritated when people write a whole post as a single sentence, without any capitals, punctuation or other breaks, and I have to decipher what they are saying.
