whatsapp’s killer feature was “no killer features, just a messaging app with number-bound IDs and good UI that even my grandma can use with minimal setup”. for anything like that again I’d change, but the minute they think they need to add something like numberless IDs, or stickers, or a social media feature, or a payment system, they can fuck right off.
WhatsApp killer feature was “No paying for SMS ever, just your data bills”, which was much lower than SMS fees in many many countries, which also explains the popularity of WhatsApp outside of the USA and in many Asian countries.
And it was tied to your phone number instead of a login ID, so anyone with a WhatsApp sign up could interact anyone else who had it, instead of having to find your contacts again like with a new IM service.

WhatsApps main “killer feature” was being early in the market to quickly reach a critical user mass.
Doesn’t matter which competitor, people will install an alternative, see that only 5-10% of their contacts have it and will immediately uninstall.
I see potential in preinstalled messaging apps. But it needs to be cross-compatible between iOS and Android. Otherwise it won’t fly.
