It seems to me that it is in the favor of Google to gather the most up-to date maps, even if they can offer them in a limited window.
I wonder if the same is true for Google Earth, since I believe that uses higher quality / different maps in a lot of area's. (don't have it so I can't check)
I do understand that it's sad they don't calculate orthographic images from that to replace their satellite views in these areas though; full 3D is severely more resource intensive on the client after all.
Visited Lisboa last summer, the building where I booked an apartment was not even there in Google Maps, satellite image data was showing a leveled site with some dumpsters.
Just checked and the images are still the same old ones...
Its actually not that difficult. I used to fly a satellite that could photograph anywhere in the world at least once every few days.

They have the resources to spend (to them) a small amount to confirm/check a play before they make it, it's been a thing since commercial satellite imaging became a thing.
Hell the (somewhat terrible but somehow enjoyable) TV show Billions had it as a plot point years ago.
For Epstein island the US government has scrubbed/redated large periods of historic satellite imagery in order to hide construction of underground structures on each corner of the island. Chinese equivalents of Google earth offer clear images of different construction stages that the "US Coast Guard" prefers to hide.
If you check different satellite imagery providers it's always interesting to see what time periods are even available (paid or free), and if the imagery from an earlier date has been re-labeled to suggest it was taken at a later date.
