"Just because the implications exist on e621" is not a valid reason to add implication tags to e6ai as well. You are not thinking about how it can benefit the community when you act that way.

The reason you should provide for making these types of BURs should be: "Why is it useful for the e6ai community to add parent copyright company tag to all franchises that doesn't respect the Tag What You See rule, isn't useful for future AI training and isn't even useful for searching and narrowing down content you want to see."

Until someone can provide me with an example why a company name would ever be useful for finding content they like more easily on e6ai, I'm still fairly opposed to enforcing copyright tags on art that isn't even subject to copyright under the current law.
