This is a very relevant topic; privacy and unrestricted access are important, especially for students or staff who rely on online portals. I think a service like BlockAway could help students using academic portals when their local network has restrictions.
For example, students at MKU using their student portal sometimes struggle with connectivity or restrictions; having a lightweight proxy might help. I explain how the student portal works here: https://mkustudentportal.net/
It would be great if proxy services and educational portals worked together to ensure smooth access to learning resources for everyone.
