For sure there are some challenges in some instances but there are always work arounds or better ways.A7iii has usb c which you can connect to computer for direct download off the camera. Not sure how quick it is tho.
off load to cloud with RAW file that can be 100mb will eat up any mobile data plan like mad and also you need fibre connection to be able to download it to PC faster than SD speeds.
e.g. how many people are there who own a camera that produces 100mb RAW files and don't have a fast/fibre internet connection?
In terms of mobile data usage - the solution there is to have an option to locally store files only, until connected to a WiFi network.
Cloud storage is a win for the customer and a win for the camera maker.
It gives the camera maker the ability to 'lock in' users to their systems through a simple cloud storage sub. It would go someway to improve their revenue too
