After reading your post I'm able to realize how much dependent I'm on MS word and Grammarly. When the first mobile text revolution started I used to hate people who use half text and send a message. I used to think why can't these people type the full word and send. But gradually the virus spreads a lot and most of the people here are comfortable using short words. I don't think we will be able to do anything about it.
Maybe one possible solution is to make them well versed in grammar in the young age itself.
