Why is the title Doll's Frontline

According to the source cited on Wikipedia, the original trademark holders agreed to transfer the title. They decided, however, to transfer to someone else who paid them for it and snapped it up in time. I do not know who the "third-party" is, but I can only assume it can be tied to the usual suspects subverting any "problematic" storytelling across the globe. You know the ones. They change dubs to push western ideology, change subtitles to be less "problematic", and have even infiltrated Japanese companies like Nintendo, Capcom, and various anime and manga companies, under the guise of a global "ESG" score. Basically they threaten to hurt your brand unless you accept their donation and change your content to push western messages and have less Japanese humor or ecchi content.
