IDF claims this practice is forbidden
Literally a supreme court decision - https://www.nytimes.com/2005/10/06/international/middleeast/israel-bans-use-of-palestinian-civilians-as-human.html (yes it was official policy and the idf appealed after being told to stop)
Wikipedia can also be useful to find software - e.g.:
or look at the Wikipedia page for whatever you want to replace and see if it’s in a category such as https://en.wikipedia.org/wiki/Category:Audio_editing_software_for_Linux
You can even do this with things that aren’t software, e.g. Homebase -> UK home improvement stores -> Screwfix.
