I think your third point is what I've had to attune to when criticizing cloud dependence. I think if your entire source of revenue is dependent on AWS then you should be prepared for 16+ hours of downtime per year. Individuals notice it more when something is down for hours but with good observability I am guessing the business notices it more when performance drags for the other 8742 hours of the year. Bursts of downtime per day can still be attributed to the device, wifi, ISP, or some other intermediary's DNS/BGP. If your margins are so tight that 16 hours of downtime will bankrupt you then I think either: a) I have no idea how to run a business; or b) you have no idea how to run a business. I'm also biased because I love highly fault-tolerant, geo-redundant, durable systems much more than "good enough for this KPI".
