Earlier quoted context omitted.

When you are online anyone can check it. There is no option to hide the online status. Using an easy script anyone can then spy and understand pretty much everything of a person, or a group. This is easy cyber stalking and dangerous. Especially because normal people do not understand this and think that hiding last seen is useful to avoid being stalked…

You can absolutely hide it - it's in the settings, as mentioned in the article. The tradeoff is you won't be able to see anyone else's status. I do agree I don't particularly like that it's on by default.

The parent commenter is talking about the "currently online" indicator, which can't be disabled. From a (strangely worded) WhatsApp doc:

> Please note you can't hide your online.

I've been using WhatsApp for years, reluctantly since it is the de-facto SMS standard in my country. I will never, ever, understand the "online" status feature. It is ridiculously invasive and cannot ever be turned off or even hidden from specific contacts. This is a SMS client, not a chat client, and revealing a user's online status is highly problematic both socially and security-wise. I can't help but wonder how m…

> since it is the de-facto SMS standard in my country.

Same in my country, I don't think Americans (or the American tech culture) realise how ubiquitous WhatsApp is in Europe and around the world.

I totally agree. Except that I very much call it a chat client. It is way beyond SMS.

It's sms that is way behind the needs of chat :)

>Nobody uses Signal in France [from the 5000 sample]

If one would've come to HN and read the last few months worth of posts you'd come to think that a lot of people from around the world moved to Signal. But then again this is a reminder about how little HN represents compared to the general population's tech choices.

My anecdata but, my friend in France does and has been forever. That's how her and I keep in contact and video chat. Perhaps their sample wasn't representative.

I had done same thing around this in 2019. This doesn't stop at this. There were quite correlation that I was able to find with basic setup The results can be quite horrifying as you can predict plethora of things. - When is someone sleeping. - When they're working,etc. - If two person are talking to each other in closed group.

Can you share that research? Seems interesting

I'd say a sample of 5000 random phone numbers is more representative than individual comments from a community obsessed (in a positive way) with privacy.

Is there any chance that the client needs the online status for some internal optimization, e.g. in order to deliver messages for online contacts to a different server than those destined for offline contacts? I could imagine delivery paths to be quite different (one would be immediately passed through in-memory while the other would be stored in some database and potentially trigger mobile push notifications).

In that case, it is nice to at least visually expose that this information is available to bad actors using custom clients too.

However, this fails as a possible excuse ever since Facebook acquired WhatsApp, given that they have essentially unlimited resources available and could easily implement a privacy proxy to hide this information from clients.

In any case there cannot be a good reason to share the online status / last seen date before any interaction has happened between two contacts, and approved by the receiver.

If you have had no interaction with someone, you should first accept a message (and not report it as spam) before this information is shared. Ideally that would be the default as well for the About field and the profile picture.

Compared to how many of those numbers have Whatsapp (1750), it's more popular than I'd have guessed. 1 Signal user for every 18 Whatsapp users
