Bevan  filed a deletion request for ttf-ms-win10 :
The latest comment on this package violates copyrights. I would have removed it myself but unfortunately I can't. I think in the old AUR this was possible... However, please remove the latest comment from azurata or remove the whole package if this is not possible.

Request #4102 has been rejected by arcanis :
