So are you able to view content, but pay to download? If that's the case, I could probably write a scraper for the site.

If you have to pay to even see the content, then you may have a bigger problem. Try pooling resources with some of your fellow students, to have one person download all the content, and then make it available to everyone else.

Another option is to expose your instructors. There's a high probability that they are getting kickbacks, especially if this is at college level. Maybe in the form of 10% of each dollar spent by one of their students. Or, they might be getting free equipment or content from Docsity, in exchange for forcing students to use it, and offloading the costs to students.

When I was in college, one of my instructors used these "clickers" that cost students $40 per semester to rent. They used radio to allow submitting realtime quiz answers during class. Students were scored on how many questions they answered, not whether they were correct. If you didn't pay the clicker fee, you lost that 10% of your final grade.

I was suspicious, so I looked into it. It wasn't hard. The clicker manufacturer advertised kickbacks on their own website.

Im not on desktop so this is more of a guess than an actual solution but Ill try to make it easy to understand.

They have what looks like a rendering filter over the javascript (docs are loaded with JS so JS blocking doesn't work.) So in theory they have the source file linked in the javascript so if you find that link to the file, you can do that using the inspecter tool. you could download it using something like wget.

Another option would be google dorks as they may have made some files accidentaly public.

Get in touch with someone who already paid it and offer them a reasonable(it may vary from one person to another) % of the original amount to them.

Or you can coordinate with some other people and bought it splitting the cost.
