This isn’t speaking, but writing (or typing). Using ‘correct’ spelling & grammar helps ESL speakers read the language as well as those relying on text translation software. Some folks make typos & it’s fine to make mistakes but it’s also strange to act like it’s just as easy to understand. Apostrophes have a specific meaning & many folks rely on them for understanding.

I’m learning a foreign language now & I can tell you it is a massive stumbling block when you run into what you think is a new word, but is ‘just’ a misspelling.
