The thread you linked to is quite old, and relates to what amounted to be a failed test:
Satellite view has been available for some time - however - The recent addition of dark mode changed the underlying style switcher in a way that pushed satellite view into the realm of Supporter Features. Rather than a flat toggle between map/satellite, there are now a number of different styles to choose from (dark, dim, light, regular, satellite).
As can so often be the case, right after I released my dark mode style, the mapping tool I use (Mapbox) released their core style update which added several new options. I’m poking around to see if I can release a test version of that to show people… It’ll basically be https://labs.mapbox.com/standard-style/?lightPreset=night#14.18/48.85362/2.29567/-58.4 but without any of the 3D elements (the camera pitch is disabled in CityStrides).
