Transactions on ethereum get processed from the mempool in order of who wants to pay the most gas to have their stuff processed.
And yes, ethereum has more potential for problems, it's a much more complicated system than bitcoin. Their current goals are proof of stake (getting away from energy wasting mining) and scalability.

You know cmake exists because "make && make install" by isn't usually that easy, anything beyond a small CLI has a lot of dependencies, and breaks with minor version changes?

It's not about how fast you can task a satellite and get data back that the article is talking about.
It's taking about between when the satellite was launched, and when it was able to send images back down was 58 hours. That is impressive. In the past it would normally take a week or more to get a satellite into a stable orbit and do all the checkout tests. After that, sure, task away and get all the images you want.
Targeting the $10-15 price range per month for the lower tiers is ideal. This would basically sit just under adobe's costs, but there wouldn't be the time investment of learning their tools, and the user doesn't need a beefy computer. There's also a good possibility that a small chunk of potential customers may only be using a phone.
