How to select all photos in iCloud

So, I’ve figured out why Apple is being so (for better terms) darn, ugh!!!! It’s a simple psychological discouragement to attempt to prevent users from storing photos on another storage platform so Apple can capitalize charging storage space. Let’s take Google Drive and Dropbox for example. Those platforms are full of functionality and the ability to transfer files in bulk indiscriminately. But with iCloud when you run out of the storage space you currently have, guess what? You can buy more... smh. The more pics you add, the more monthly storage space they will ultimately charge. Like seriously, who’s gonna sit there and individually select 500+ pics, heck, 300+ pics for that matter. It’s M.O.N.E.Y. Apple, MONEY! Not a concern with functionality or accessibility. The ability to multiple select is disabled for a reason guys. After I download these remaining photos guess what, yeah, goodbye iCloud.
