Perhaps someone should come up with a small <5-line snippet that explains some portion of how to defeat Widevine, and then everyone in Israel should, I don't know, configure every mail server they know of to autoinject the fragment into all outgoing mail, or something. And/or configure everyone's browsers to autoinject it into every modified multiline text input field (maybe).
Obviously it wouldn't be able to last. But it would be VERY good publicity. And the thing is, Widevine would constantly be being updated so the instructions would constantly break and need to be changed, so exact-string filtering wouldn't work ;)
So. I'll start, despite not living in Israel: both Chromium and Firefox will use PulseAudio if it's available, and fake soundcard drivers exist for Windows/macOS as well, so sound isn't really problem if you're prepared for an "export" process that takes as long as eg SpotAHEM tracks take to play.
