Good far-sight. But it helps to keep in mind that most of the legacy app users that have that goal, also have an immediate need to continue engagement with their current audience that have no interest nor awareness to transition to another/newer app.

If the Nostr meets the need of the user, they will come. If the need of the user is a specific engaging audience… it may not be here for them just yet.

And it could be possible that legacy apps are more aggressive with development when people start migrating away from them… which encourages them to incorporate the ideas and designs of the competition that their current users have proven to be attracted to.
