Let's assume that I have an iPhone and
- I tell how to use it (e.g. how an app is downloaded, how a photo is taken),
- I mention about its functions, features (e.g. how a contact is created, how Wi-Fi is disconnected),
- I tell use, functions, features of another downloaded software from App Store,
- I show built-in and downloaded software's screens, screen images, screen video records, symbols, logos, functions, features etc.
in my blog webpage which made money via Google AdSense and/or affiliate marketing or on YouTube which made money via Google AdSense and/or affiliate marketing or on Udemy which made money by selling courses.
Or, let's assume, I have a Windows 10 on my desktop and I do same thing (e.g. selling C language course on Udemy by using Code::Blocks or selling complete Windows 10 course on Udemy).
Or, let's assume, I have a Linux disto on my laptop and I do same thing (e.g. publishing how a virtual machine is created by using VirtualBox on the blog which made money or selling complete VirtualBox course on Udemy).
As you predict, much more combinations can be produced.
Can you please explain what the rights are of the software owners in this case?
EDIT:
You can think that I buy the software if it requires something like a key and if I want to handle them on the platforms as in the way I mentioned. E.g. Windows 10
EDIT 2:
I mean people or companies who provide a software, such as PuTTY, VirtualBox or WhatsApp, by software owners.
