What do you mean, there are many resources that provide access to various satellite images. In general satellite imaging is not really that sort of hushhush industry it maybe was 50 years ago.
But I can imagine it all depends on jurisdiction. A Russian or Chinese satellite imagery company will have no problem publishing clear images of US military bases, while an American satellite company may have to comply with US laws prohibiting that.
And vice versa.
Ultimately if you cobble together imagery from multiple sources, you can probably get everything you want.
