I'd definitely say both. Communicating over the internet of course is easier for a lot of autistic people, and I'd say it helps make it easier to connect and in some ways has spread information and awareness (I feel like there's a better term for that, but can't think of it?) in a positive way. But then there's the whole trend of using "autistic" as an insult, and the other ways in which social media can be harmful in general, i.e. bullying and such. Also the way that it seems some parents of autistic kids like to use social media to post questionable things/put things about their kid on display without considering the kid's privacy enough.
Same question.
