Because it's easier to use the version that's in the distro, and why do I need an extra set of libraries filling up my disk.
I see flatpack as a last resort, where I trade disk space for convenience, because you end up with a whole OS worth of flatpack dependencies (10+ GB) on your disk after a few upgrade cycles.
For a lot of project "compiling yourself", while obviously more involved than running some magic install command, is really not that tedious. Good projects have decent documentation in that regard and usually streamline everything down to a few things to configure and be done with it.
What's aggravating is projects that explicitly go out of their way to make building them difficult, removing existing documentation and helper tools and replacing them with "use whatever we decided to use". I hate these.
99% of the time it's just "make && sudo make install" or something like that. Anything bigger or more complicated typically has a native package anyway.
I mean it's 2024. I regularly download archives that are several tens or even over 100 GB and then completely forget they're sitting on my drive, because I don't notice it when the drive is 4TB. Last time I cared about 10GB here and there was in the late-2000s.
Yep that's all well and good, but what flatpack doesn't do automatically is clean up unused libs/dependencies, over time you end up with several versions of the same libs. When the apps are upgraded they get the latest version of their dependency and leave the old behind.
I don't know what dependencies he has but my 3 year old system that is constantly being updated is full of flatpaks and all of the dependencies combined are only around 3GB. People see 1GB of dependencies and lose their mind.

I change my opinion depending on which app it is. I use KDE, so any KDE app will be installed natively for sure for perfect integration. Stuff like grub costumizer etc all native. Steam, Lutris, GIMP, Discord, chrome, firefox, telegram? Flatpak, all of those. They don't need perfect integration and I prefer the stability, easy upgrades and ease of uninstall of flatpak. Native is used when OS integration is a must. Flatpak for everything else. Especially since sometimes the distro's package is months/years old... prefering distro packages for everything should be a thing of the past.
