m040601 [1] filed a deletion request for oysttyer-git [2]: Tool no longer maintained. This PKBUILD has not been touched in almost ten years. The same for the repo, https://github.com/oysttyer/oysttyer, which explicitly says at the top
``` Since Twitter is disabling free API access, I am admitting what has been the case for years: oysttyer is no longer maintained. ``` [1] https://aur.archlinux.org/account/m040601/ [2] https://aur.archlinux.org/pkgbase/oysttyer-git/
