I think there's a difference in that dropbox was targeted at regular users, not just developers.
I think docker desktop and apple's containerization are both targeted firmly at developers only.
It's like programming, sure it's possible to write code in microsoft office or xcode or vscode, but all programmers I've met opt for ed or vi.
Developers are users as well, I don't get the macho thing that developers always have to do it the hard way.
I don't get the thing that by default present cli usage as hard way compared to gui.
This can sometimes be true, but on many ocasion be the opposite: For instance I've been spending 3 hours watching an IT support techician seemingly clicking randomly everywhere to debug why the corporate sec/antivirus on my laptop is saying my configuration is not compliant. The provided gui and accompanied interface to check events is strikingly uninformative, slow and inefficient and having a simple cli tool with a -status or -report flag that would give you the reason it complain would be much easier to everyone involved.
You're assuming that the CLI tool would be any better, which in many cases are just as bad when coming from the same company.
