It's plausible this took effort, so I think it's only fair if they license it - it seems also ethically fair, since their licence is permissive.
Realistically it unlikely that anyone would attempt to decompile and fully reverse engineer excel and attempt to package it as a product that they own. It just doesn’t make sense practically. But throwing something in Jira isn’t the same thing as actually putting in the work to reverse engineer it and make it effectively a perfect replication. You don’t unbake the cake, you can’t. You just figure out a process to end up with the same cake.
As for TOS goes, that’s its own other legal issue that has a mixed history erring on the side of TOS not actually being enforceable.
The people who did this work I think are fine to ask people to respect their license. They don’t have to worry about the US/Israel knocking at the door to tell them they can’t claim ownership anyways.
