I would just like to share a story, and probably an opinion as well. When I was doing my STEM undergraduate degree a couple of years ago, I took a course in which I had to use MATLAB. I won't disclose too much information, but it was a course involving computation.
Well, we (the students) weren't given a student/institutional license of any sort, but the course coordinator still insisted on using MATLAB. We took it as an implicit instruction to "somehow" obtain MATLAB. In the end, one guy in our class pirated it and distributed it the whole class.
Before that though, I did approach my course coordinator, asking them if it's possible to use other software like GNU Octave, which is a clone of MATLAB. Personally I think it should also possible to use any other programming language like Python for example, since the important part is the computation part, in my opinion. They refused any discussion and did not even consider alternatives, instead basically forcing us to "obtain" MATLAB. How else? Well.
As I have said, we all pirated it in the end.
I did something quite interesting though, which is that for every quiz, assignment, and projects that we had, I'll run the same exact MATLAB code on GNU Octave, to see if it's compatible. And it is. It works flawlessly. There's only one function that GNU Octave didn't support back the (this was a couple of years ago), and even then, it wasn't an essential feature, you could use other software for that function as well.
By the end of that semester, I had compiled almost all input/output of the MATLAB code alongside its GNU Octave's counterpart, to demonstrate that we didn't need to pirate MATLAB to get through this undergraduate course.
Regrettably though, I didn't follow through. So sad!
Do you think piracy is justified in this case?
You are right, of course, the people who labored to make the things should be compensated if they want to be.
What's at issue is that if you own something you can do as you please with it. Once the electricity has been delivered I can charge batteries with it or power lights or give it to my neighbor for free if we agree to do so. I should be able to buy a piece of software and back it up or give it to my neighbor, or any random person I choose if I own it. I would buy much more media if I could just own it and do as I please with it, but because of DRM and the greed of companies that distribute the media most times you can only rent it. Piracy is in resurgence because it is becoming so difficult and expensive to just pay for the media.
I pay for Netflix, so I think I am entitled to whatever is on the service. If I have a copy of a Netflix show on my hard drive in 4k, am I taking something from Netflix? What about when I watch that show in VLC because I'm on an airplane? What about when I let the man next to me have a copy so he can watch it on his device?
While I have plenty of disposable income these days to spend on media, they simply do not sell the product that I want, and if I did not have the other means of accessing that content I doubt I would pay for Netflix.

I hope the tone of my comments do not come across as negative, I am trying to illustrate my thoughts on the subject, not argue, and I find questions more illuminating than just explanations.

edit: i guess the OP was about software and this rant doesnt really apply
Software-wise I dont pirate that because I try to only use open source software, for mostly the same reasons of disliking DRM and prefering to own things.
