> It's not truly convenient if you're stuck with it.

That's a bit extreme. I would say that it's only inconvenient if you need/want to switch - everyone can make a guess about the probability that they will want to switch in the future, what effort it would take and whether that's worth it for the value they will get in the meantime.

That works great if you're a nerd and only every communicate with other nerds. Once you try to talk to moms, your stuck using FB or messages. So, you can be definitely use the most secure stuff out there that gives you all the freedom to do exactly what you want, but you'll be on that island all by yourself. Enjoy

my mum is too much of a normie to use computers regularly at all, which helps

she either calls or messages, which from the lock-in standpoint is just better and perfectly adequate - it means much less spurious messaging

But that's a trade-off that most users are expected to have. I like how macOS can handle continuity of applications (iMessage, Apps, Fileshare) across multiple devices. I haven't seen any other OSs or ecosystem handle this as well as Apple's.

The service known as the Internet taught me this.
