>>94097754To actually argue the points:
1. Financially, OG songs are costly and time-consuming, which is why original songs can be so rare. It is why it took most of the Advent members a year until they had an original song. As well, some talents (Gura, Fauna, etc.) only have/had a few original song simply because they don't want to do all of the hullabaloo required for an OG.
2. Terrible idea. Firstly, this is only a further reason to leave Cover, as a member might want to sing a cover song, then be denied in all cases, rather than specific cases. Secondly, financially, songs are a great way to get subs views, and money from ads and Premium, as songs will be put in playlists and relistened to on repeat. Covers are taking a known success, and applying them to the hololive member, and come out faster. Justice has only one OG song between the 4 members sung by all 4, Advent has only 7 originals songs, with three from Nerissa and 2 group songs, and the non-singing Promise and Myth members (so not Calli, Irys, and Bae) would only have at most 3 songs only sung by each member. When you compare that to long-standing indies and other Corpos, which have covers, there would be less of a reason to watch a Cover member and for the algorithm to boost them.
3. I don't actually know of many hololive songs being covered by other talents, much less ex-holos. Clearly, other people singing hololive songs doesn't make someone successful, so why would ex-holos be affected that massively by this. The only outcome would be that some corpo or large indie would try to license a song as a promise, get denied, then cause huge drama on twitter. (You wouldn't really be able to only target ex-holos due to how contracts works. What if a ex-holo joins a corpo, like Vshojo, and then the corpo asks to use the song for a group including the ex-member without necessarily acknowledging or knowing the rules?)
If anything, these would only boost the 'traitors' (ex-hololive members) success as they can sing viral and popular songs unlike the hololive members.
