Subject: 2026 white paper on EPICS vs commercial SCADA software

Dear EPICS community, 

I recently came across a new whitepaper that present a comparative evaluation of EPICS against various commercial SCADA platform alternatives. The evaluation uses a set of requirements that they state are representative of the IFMIF-DONES plant currently being constructed in Escúzar, Granada, Spain.  The paper is linked below.  If you have a moment and are inclined, please take a look at Table 2 and Figure 3 and let me know if you feel that EPICS has been rated accurately/fairly.

"A comparative study of industrial and open-source SCADAs to optimize the design of control systems for the IFMIF-DONES plant"

Note - Figure 3 shows EPICS as seriously deficient as compared to commercial SCADA software, but then I saw what they said on Table 2 requirement #17 wrt video and it doesn't seem like they fully understood EPICS well enough to give it an honest rating.  

The paper is being circulated within my organization as strong evidence that EPICS is a poor option as a control system SCADA for a facility.  Any insights this community can provide in explaining the possible motivations of  the authors and/or highlighting any clear bias or incorrect assessments that the paper may contain would be much appreciated.

Thanks in advance.
