Fig relies on free labour to add completions and does not support open-source completion formats
Fig is VC-funded and at some point will have to generate revenue for it’s investors - at your cost
don’t use Fig!
if you have zsh you can use zsh-autocomplete, which is no worse than Fig

edit: this comment was the most popular before HN moderators pinned it down, turns out Fig is YC-sponsored, so i’m not surprised
