Sure, I can totally believe that Threads is a dystopian wasteland of vapid influencer "content" and no content of interest. But if the theory is that you need Mastodon to bring in the interesting content because their 100M userbase can't or won't produce that content, the federation would be needed indefinitely. It won't be that federating with Mastodon for a year bootstraps their own content production. If people writing interesting things aren't willing to go to a platform with 100M users now, they won't be willing to do it in an year either.
