This bit about GPL vs. BSD is interesting: The GNU General Public License that would create additional legal complications for Beckhoff’s customers as well as force Beckhoff to share their proprietary real-time, TwinCAT, which runs in kernel-mode. Would they need to share the TwinCAT source code if they were to use Linux? Nvidia gets around this requirement with dynamically loaded binary blobs. Or to pose a different but related question, do all eBPF programs need to be open-sourced rather than distributed as bytecode only because they run in kernel mode?
