WhatsApp can be installed on any device. iMessage requires specific hardware, i.e. an Apple iPhone.
It is always possible not to use either and just communicate by SMS (which I prefer myself, but as I understand it WhatsApp came to be used here in Belgium because phone plans are expensive and SMS are still limited/paid on most plans) but that's a different matter.
The matter here is that the commenter I was responding to says I don't exist. My experience is that folks with that attitude also treat me as if I don't exist. I object to both of these things.
Selling your first-born rights for a lentil soup, or agreeing to adversarial T&C of a foreign corporation should not be a precondition for participating in a society.
Well, as a parent it really is difficult, you constantly have to explain yourself and arrange alternatives. Some context: Texting (SMSing we call it) is f-ing expensive here, ridiculous (25 ct/message? Unless you buy a plan, but why should you? There is Whatsapp... Nobody is going to use SMS with you, any parent will probably think: "Are you making me send an SMS [to come pick up your kid], really?").
The green bubble effect is because some people do not want or cannot afford an Apple phone. There's a huge difference.
If Whatsapp came with a €400 base price and roughly 50% of people using something else, I'd understand.
But its a steep upward slope to climb. Lots of data-siphoning apps are painted on buses or splash on city ad "walls" but whatsapp is actually a permanent fixture of the urban landscape in so-called "neighbourhood watch signs". A creepy dystopic image if there was one.
It's hard to understand it if you don't live in NL just how extremely omnipresent WhatsApp is. People use it for everything, from casual family chatter to highly serious conversations to quite literally business-related conversations. Not having WA will absolutely result in things like missing crucial information because "we send it in the WhatsApp group" and that of course in turn will be used as a mark against you when you're say, seeking a job.
This occurred before Facebook bought it and their recent T&S change that allows them to use WA usage to improve their algorithms basically was a case of "enjoy being forced to share your data with no recourse". There was tons of social pushback about it but nobody could do anything about it because the app is so entrenched.
I am thoroughly looking forward to the DMA and its impact on WhatsApp.
At the same time, the OP is not in a "bubble". You can't call something a bubble if almost everybody is inside it.
Could you please stop making my life harder? No, not "literally everyone" has Whatsapp: I don't. Agreeing to T&C of some foreign corporation should not be a precondition to participating in the society, don't you think?
