“I want and sometimes need to know when someone has read my WhatsApp message. I need to know when it's a work thing so that I can phone instead. Sometimes the 'last online' thing is helpful when you're worried a friend might have dropped dead (living alone / in another country)."
As others have said, blue ticks just mean the message has been opened, they don’t guarantee it’s been read. People can click on a message by accident, desktop apps can mark messages as read when the recipient isn’t even in the building.
You could ask people to acknowledge messages, if it’s important, rather than monitoring their activity and coming to (possibly incorrect) conclusions based on blue ticks or their ‘last seen’ time.
“It's not about controlling these people. It's like saying you're controlling to want to know when your tracked Royal Mail parcel was delivered. Do the recipients of the parcels object to this?”
Royal Mail telling you your parcel has been delivered is the equivalent of two grey ticks. You know their phone is on, they have signal, and the message has arrived.
I don’t object to that.
I would object to a tracking service that automatically notifies the sender as soon as I start to open the parcel, though.
I turned my read receipts, last seen and online status off one day when I was very busy, but one of my children was messaging about something important to them. While dealing with that, I had a message from a friend asking why I hadn’t looked at what she’d sent hours earlier, pointing out that I was “constantly online”. I didn’t have time to chat, I had to prioritise what I was doing, but seeing I was online and not communicating led to her feeling like I was ignoring her.
The ability to track my activity felt intrusive, and was causing unnecessary stress that could easily be avoided by changing a couple of settings.
Nobody needs to know when I’m engaged in conversation with other people, when I've clicked on a message, or when I last opened an app. It seems removing the option for people to monitor when I’ve looked at my phone is considered weirdly controlling and secretive (or, my personal favourite, demonstrates “a lack of confidence or a manipulative personality”) by some on here though 🤷♀️
