The amount of FOSS snobbery in this community is hilarious. You typed that comment on a proprietary device with proprietary hardware, probably running proprietary software (unless you’re on Linux, truly using ALL open source stuff, including RISC-V hardware, FOSS browser and network stack). But God forbid an app is just source available instead of truly FOSS. Gasp! The horror! You should complain about it using one of the completely closed-source Android/iPhone apps that you use every day.
