WhatsApp introduces ads in its app

I have a couple of friends that I message via Signal and even convinced my dad to use it a while back, but here in Brazil WhatsApp is _everything_, and I doubt most people care about this at all. In my case, I'd love to just go over to Signal fully but then I couldn't talk to family, friends, and probably couldn't even book a haircut or pay my taxes (my accountant messages me on WhatsApp).

It's one of those where unless just about everyone were to go over to Signal, most people won't, because keeping track of messages in two apps is quite hard.

That leaves me stuck in this ecosystem, which is quite sad.

The unfortunate reality is that most people won’t follow you. Not because they don’t respect you or your concerns, but because the cost—in effort, friction, or just breaking habitual patterns—is too high. Social coordination is fragile, and it leans heavily on lowest-common-denominator tools. WhatsApp has become that denominator.

What’s likely to happen is this: group chats will move on without you. Events will get planned. Conversations will unfold. People aren’t going to message you separately to accommodate your principled stand—not out of malice, but out of convenience and momentum. You’ll be increasingly left out, not because anyone wants to isolate you, but because ecosystems don't fracture easily.

After a few months of being disconnected and missing out, there’s a strong chance you’ll reinstall WhatsApp—not because you’ve changed your mind, but because opting out of a near-universal platform means opting out of modern social participation.

This isn’t a defeat of principle—it’s a reflection of how network effects work. The only way to realistically challenge something like WhatsApp is if a critical mass moves at once. Individual protest, while noble, often just leads to isolation unless it becomes collective action.
