You can blame the no text chat on some stupid ADA compliance law that passed towards the end of the Obama presidency. Basically makes it so that if you want people to be able to type to each other, it opens a whole goddamn can of worms about supporting people who can't type.

Like a lot of laws, instead of making it so that people who can't type get some sort of support making it easier to communicate ... it makes it so that nobody gets text chat at all.
