I’m no academic, but it seems wrong to me that any field would require the use of a particular proprietary software in order to do one’s homework assignments.
May Excel or SPSS be the best tool for the job? In many cases, sure! But students should be allowed to use whatever other software can also get the job done, as long as the software exports the assignment in a data format that the professor can reasonably ingest (e.g.: turning in a CSV file, which can be understood by many different kinds of software, not just Excel).
I understand professors have limited time to check homework and thus don’t want to spend time learning how to do anything but open a single, specific filetype, but that’s besides the point.
I understand that; my position is more ideological than practical. In an ideal scenario, AutoDesk, Adobe, Microsoft, etc wouldn’t be so deeply entrenched in their respective fields such that they are the de-facto tools of the trade for every business which must be learned in order to be hired. I know a given student has to learn certain proprietary tools in the current academic and professional environment. My comment was saying I would prefer this not to be the case. I am fully aware that proprietary software domination in the academic and professional spaces is not going away any time soon.
In my ideal scenario, an interviewer at a company would ask, “Can you perform the following edits to a given graphic?” instead of “Can you use Photoshop?” since the former allows for candidates who can use alternatives like GIMP. I understand company pipelines aren’t set up for this, either, because company pipelines are also deeply entrenched in proprietary software.
The OP’s photo is specifically about professors allowing other software to be used. Which would be a good starting point for making these kinds of changes.
