The reason why is because of dependency hell and general packaging conflicts that could occur. You can go with the tar, snap, appimage or flatpak. If you do decide to use the system level package from a 3rd party, just be aware of the risks and be careful. The issue lay within the difference in standards, the usual target for these companies is Debian using the Debian packaging guidelines, while Ubuntu has their own, Ubuntu and Debian also have different releases cycles with can lead to conflict with certain packages.
Perhaps, if you’re needs aren’t met maybe moving to a semi-rolling or rolling distro is best.
