yes, mapbox small screen attribution is generally an issue. The reason they do not have or believe they do not have sufficient space for attribution is that they use a quite long string:
“(c) mapbox (c) OpenStreetMap Improve this map”.
MB could, on small screens, waive the textual MB attribution requirement (because there is already a mapbox image logo), and also the “Improve this Map”-link (or expand both on hover/tap), and there would be sufficient space for an always visible (c) OpenStreetMap (plus the mapbox logo).
Or make it 2 rows as fits.
Or hide the Mapbox attribution logo behind a click-to-show-“i”   ;-)

It is not a technical restriction that MB doesn’t show the expanded attribution, it is rather a result of the other UI choices they made.

the license doesn’t limit attribution requirements to bigger map sizes, they could put an attribution string below the map if they don’t want it on the map for legibility reasons.
If these small maps were limited to one or two instances they would probably be ok under the substantial guideline, but as there are literally hundreds of millions or even billions of them, we should not let them pass as is.
