Than and that?

Has anyone else noticed that people are now starting to replace the word "than" with "that," such as in "Donald Trump has more money that me"? It is "more than"! I understand there are some ambiguous points in grammar, but this is just nonsensical. It can't be a typo because the T and the N are no where near each other on the keyboard and I have been seeing it everywhere, and not just on the web, but in published books. It is like the product of some conspiracy. I feel like I need to start a movement against it. Start looking and you will notice it too.Does anyone have any idea where this is coming from? Is there any possible way that this could be valid?
