There is cross-platform play between PC (including Linux and Mac) and mobile devices (iOS and Android). For other platforms like Nintendo Switch and Xbox, crossplay is not available, meaning you can only play with others on the same console
You should be able to play co-op across PCs regardless of OS but console versions are not cross compatible.
And what do you mean people with pets or special needs are not able to protect themselves? Ever heard of a radio? One of many things you can use to drown out the shots for pets. Or are you just sitting your pets on the window and pointing at the beautifully ligthened sky while the poor pet shivers beside you, like psychopats?
And for people - headphones exist. It’s literally one night a year.

Density and cultural norms in general are definitely a factor.
If I was out and about in my normal area where I live in the US and someone got close enough to pick my pocket I’d be on high alert because they are way inside the normal personal space bubble here.
