Its required for self promotion, there is no way for a third party to know the details to tag and disclose.
It would be like posting plex feature updates. There is no way for the poster to know whether or not any AI was used in development (though given the Plex trajectory, we all know, but thats a different matter).
I’d be more worried about not using it, personally.
That said, storing videos isn’t the only use. I have a… fairly large NAS, and it has photos/videos I’ve taken (including the raws for some of my dslr photos), its the storage for my VMs, where my backups are stored (really a different NAS but appropriate for the discussion here) which are then backed up elsewhere as well, local git repos, etc, etc.
Is streaming all you do? If so, no, you don’t need it.
But if you do anything else, its a good place to store that data.
