Perhaps "you will have to learn a few Linux commands" was a bit judgemental. Maybe I should have said "we would like you to learn a few Linux commands" so that together we can get to the cause of the problem you came here hoping we could solve.
Windows did revolutionize the computer industry. Linux has also become a very popular operating system. It or other Unix variants are embedded in many devices we use today including most cell phones and in many of those devices, there is no need to access or use the shell commands.
The Raspberry Pi is a single board computer (SBC) that utilizes a system on a chip (SOC) but is powerful enough to run a windows-like GUI if the user so chooses but that comes with a cost. To avoid that overhead, lite versions of Linux allow for the resources of the RPi to be dedicated to specific tasks like being a front-end for a 3D printer but to do so, they sacrifice the GUI.
If the 3D printer behaves (by both design and reliability), then there is little need for access to the RPi at the shell (command) level. OctoPrint provides access to the printer via a web browser.
Unfortunately, not all 3D printers behave. Some misbehave because of poor design, others are unreliable, and sometimes they just break. When the owners of these misbehaving 3D printers come here for help, us helpers may need to use tools much as a mechanic at an auto repair shop would with one big exception, we don't have the luxury of putting our hands on the patient. Those asking for help need to get their hands "dirty" and knowing which end of the "screwdriver" to use is essential.
We don't "frown upon" those asking for help. We try and help them as best we can by providing the "tools" and how to use them. If 3D printer users just want to just drive from A to B, no one is stopping them from taking their 3D printer to a printer repair shop or having a printer repair person make a housecall when it misbehaves.
Of course, they could have a $35 controller connected to a sub $200 3D printer and the first service call will probably cost that much. Perhaps the A to B "daily drivers" should instead consider both the $35 controller and the $200 printer as commodity parts and just throw them away and buy new when they misbehave.
