DE can see usage data on their side, which is how they determine balance. For example, when they changed Carrier from a vaccuum pickup to an ammo case and made Vaccuum a precept for all Sentinels, they said something along the lines of "Carrier was 80% of all Sentinel usage across the playerbase", hence their need for that change.

The article is...slightly inaccurate, as Dispositions are not a server-side calculation but are right now a manual setting that DE updates periodically, as seen in some update patch notes a while back. They may make it more dynamic in the future as they figure out more behind how usage and Rivens change up the balance.

So far as I know, the rank change in Disposition does not affect the mods in question directly (IE I don't think your 35% fire damage mod at Neutral will become 45% if it changes to Strong overnight). I'm not sure how the actual Disposition affects the Rivens; at first I thought all Rivens had a general stat pool and Dispositions only affected how much percentage of the face stats your weapon can actually get, but now I think it affects the rolls directly in either increasing or decreasing the percentage gains.
