Frustratingly, though the article goes into how replacing/upgrading the whole control system will be an big, expensive project, they don't attempt to say why they can't just update the "read from floppy" part of the system to read the same info from a modern component.

Floppies aren't the problem, the main problem is lack of support. The MTA moved off of OS/2 back in 2008. Yeah, halfway into its intended lifespan Alcatel/Thales basically stopped supporting the whole mess. If I had to guess they're using an equally unsupported version of Windows now.
