But what am I supposed to advise them to use?
The article doesn't make any suggestions on alternatives. It links another article he wrote, which also doesn't suggest anything.
* Instagram is picture focused, which doesn't fit with 90% of my parent's posts.
* Twitter is public by default, which is less privacy than the soft-wall provided by FB "Friends". Maybe everyone could use private twitter accounts.. But the article argues
> "It (FB) is a megaphone and an amplifier of extreme views, easily disproven conspiracy theories, pseudoscience, superstition, magic cures, disinformation, controversy and hyper-effective propaganda."
If that's true of Facebook, it's certainly in abundance in twitter!
* Maybe Mastodon? They don't want or need to understand federation. None of their friends use it, so they can't keep in touch with their old co-worker from 3 jobs back.
* Discord/Telegram/Signal/Wire - They're all intended for live/dynamic use, while FB excels at async. Sure, you can go back and reply to old things, but that's not the intent or way things are typically used.
* The best I can think of right now is regular old Email.. It's pushed-based, and sends to exactly who you want it to. It handles comments (replies) and it can embed pictures/links/etc.
