Shows Default Metadata Provider

[Verme]

Hi folks, based on the latest Plex announcements, I've been searching for a replacement .. well, have been for a long time now. Jellyfin fits the bill. I'm curious though why the default metadata provider for any Shows library is the movie db .. instead of let's say the tv db. There is a plugin to add thetvdb, however it seems odd to me it's not installed/enabled/the tv default. Are there issue with Jellyfin and thetvdb preventing this? Is the movie db just better for tv as well as movies? Thanks.
