You can use the cloud with confidence...

for anything that you don't mind being publicly associated with you.

I don't mind that myself.

I mind my data being available to someone else when I marked as only for me.

Not just the cloud. Any internet connected system, whether in the cloud or on-premises, is vulnerable to intrusion, data breaches, etc.

The only system that would be somewhat trustworthy would be a totally air-gapped internal system. This used to be the norm, pre-internet. Few businesses really have this today.

Yes I worked for a totally airgapped defence contractor many years ago. It was very boring :)

It was an RF tight triple wall secure engineering facility with no windows and power filtering. Vehicles and people searched on entry and exit. They knew very well of these risks a long time ago. To give you an idea, the building was designed in the 1950s where they even had dampers on the water pipes coming on site due to the use of typewriters historically.

'The cloud' is really just a bunch of computers owned and operated by other people.

"The Cloud" is like storing your data with skywriting, you can see it from many locations, but so can your neighbors

A very poor analogy when encryption exists

Who said skywriting can't use encryption?

What skywriting uses encryption? How is that a useful metaphor for describing the downsides of "cloud storage"?

For the average cloud platform it is totally insufficient to protect you from a bad actor or stupid programmer at the provider.

Imagine if IAM had a major vulnerability suddenly...
