Why flagged

This PKGBUILD downloads a prebuilt binary .deb from dl1.tlauncher.org via a PHP redirect URL (f.php?f=...), extracts it, and installs executables into the package. The host is the official TLauncher distribution server (tlauncher.org is the upstream vendor), so this is not a random personal host. However, TLauncher itself is a controversial Minecraft launcher that has historically been associated with piracy (allowing play without a legitimate Mojang/Microsoft account) and has had malware bundled in past versions. The PHP redirect URL is somewhat obfuscated but is pinned with a sha256sum, which mitigates substitution attacks at build time. The core concern is: (1) TLauncher is widely considered a piracy-enabling tool for Minecraft, and (2) the package installs prebuilt binaries from a vendor with a poor security reputation. The sha256sum provides integrity but not authenticity. The piracy flag is borderline — TLauncher does enable playing Minecraft without a paid account, which constitutes circumvention of license enforcement, but the PKGBUILD itself does not crack anything. Given TLauncher's well-documented history of enabling unlicensed Minecraft play, the piracy flag applies.
