>Although my biggest question is... it's a fucking messenger app. Why does it produce a larger binary content than a full-blown Linux kernel?!

Because it does so much more than messaging. Also, UI code is generally very verbose.

Also, conversely, the kernel doesn't do that much. Most of the Linux kernel source consists of device drivers, which compile to modules rather than get bundled into vmlinuz. Many of these modules are also rarely built if ever. The kernel itself really is a pretty small fraction of the complete software bundle that makes a Linux system functional.

I know. But still, that amount of compiled code is insane.
