Earlier quoted context omitted.
GP said 'things are documented in' - while neither's an ideal tool for long-term product-oriented 'how its supposed to work' docs, both are definitely used like that. (You probably wouldn't choose either for that from the beginning, but you start using Jira for issue tracking/feature planning, of Figma for feature design, and end up with them holding a lasting record of how the feature is intended to be.)
“You must use this tool for this specific collaborative process” is not the same thing as “You must not use this tool at all”.
