There’s actually been a network effect especially with groups of people with being a “blue bubble” vs “green bubble”.
Doesn’t look like this has cost them financially at all.
I even feel like whenever I have to SMS someone, it feels like going backwards. It’s not encrypted, there’s no delivery receipt, no richness, etc.
I’m just amazed that Google has utterly failed to build a viable alternative on Android in 10 years (which is why all the other services have thrived there), and boy have they tried.
