How is it a nightmare? The site you linked literally just links to one of the images under here https://cdimage.debian.org/cdimage/unofficial/non-free/cd-in... , and not even the most useful one.

In view of those more-complete, non-proprietary solutions, you have to be a chump to pay for a Slack IRC bridge.
