It’s not possible for everyone to just tell if it’s supposed to be sarcasm. ADHD makes it hard. A bad day makes it hard. A tiring day makes it hard.

The downside of the misunderstanding isn’t just downvotes. It’s possibly a proliferation of misinformation and an impression that there are people who DO think that way.

Being not serious while saying something grim is not a globally understood culture either. It’s more common and acceptable in the Western world as a joke.

So… call it accessibility, but it’s just more approachable for everyone to just put an “/s”.
