Speaking from personal experience, our team originally made our own wallboard, and it was put on a big monitor in our space. Originally all was fine, the board would stop updating numbers once in a while, but nobody really cared. Just ssh into our raspberry pi, and restart the services.

Turns out that our scrum masters and product owners looked at this board when they walked by, now they wanted to see other things as well. So they started allocating developer time to build these statistics, obviously a job nobody wanted to do. So we bought an existing solution that had all the data sources we needed, and let the business manager their stats.

So yeah, I agree anyone could build it themselves, but it rarely sticks to those 1 or 2 numbers, in which case, it's cheaper to spend a couple of bucks, than have developers continue to support it.
