People also don’t type in proper punctuation because our keyboards are stuck in the olden times and most online forum and social media platforms are same old garbage what comes to typography.

I’m an amateur writer, I love it when word processors replace straight quotes (") with proper double quotes based on the language (“like this”, ”kuten näin”, «comme ça») and instead of minus (-) you get actual real dashes—as one does. But good luck implementing this on social media. Even blogware handles this pretty badly, the only way to get proper punctuation is to write the post in a word processor.
