My family use XMPP daily for messaging and calling each other, and I know many others who do the same. That's not to say my perspective is average, or that the federated XMPP network is anywhere near as popular as WhatsApp, Slack or Signal. Network effects and money are powerful forces, significantly more so when combined. Luckily for specific groups (families, organizations, etc.) who just want more control over their intra-group communications, it's typically far easier to overcome the network effect issue than solve it for the general case.
