There already exists a “Google Play licence check” permission apps can use to verify whether or not the app has been bought on a Google account that’s present on the device.
If people can crack the app to remove this (which is a thing for some of the popular apps), they’ll also figure out how to patch this out. This is strictly useful for free apps, and only serves to make it unviable to distribute verifiably clean apk’s outside of Google Play (so rip APKMirror)
I installed a KDE latex math tool that came with texlive as a dependency. Shit’s awful when doing updates.
I ended up uninstalling the tool and texlive, and installed tinytex instead. I then tabood texlive and reinstalled the tool from software.opensuse.org as the YAST GUI allows you to ignore dependencies.
It works in the KDE tool and in one note taking app with latex math support, but I haven’t tried adding new packages yet. I don’t know how good of a solution this would be if you use latex outside of just rendering a couple of equations, but it could be worth a shot
