Sorry, but for the most part this sounds stupid. You're hating a widespread method of communication because it doesn't work for you _when you're not using it_. That's like complaining that no one text messages you if you never opted in to owning a phone.
I hate that, if I somehow don’t want to consign my personal data, beliefs, preferences, relationships, work history, daily plans, and private messages to a massive advertising corporation, I have to risk missing out on seminal life events. Not being on Facebook is sort of like not having a cellphone. Sure, me and a small number of weirdos can opt out, but we are increasingly disadvantaged by it. I think that’s a good…
Shouldn't it also be the case that, if you're the one not on a widespread platform that - clearly - a lot of people are using to communicate, it's on you to make the effort to reach out?
I actually think the opposite of your claim - expecting a family who's member has committed suicide to have to actively reach out to this one person is rude and without depth. Expecting any kind of personalised treatment whilst alienating yourself is similar, but that one example sums it up for me.
