You know, your question is very interesting: no, we didn't.
Anecdote: we reverse engineered several Microsoft products and before Microsoft Windows 7 launch we were contacted by Microsoft QA and they offered us support to check if our software was compatible with it! BTW, our software was installed in millions of computers around the globe. For example, Trend Micro used our software for supporting their antivirus in Outlook Express and Windows Mail.
Our Deviare Hooking Engine [1] was eclipsed when Microsoft Detours [2] turned to an MIT license and free. Even when our was superior in several ways. This is why I wrote that you should continuously fight for "adversarial interoperability".
I agree. After receiving a C&D from Meta for my OSS project (along with some other maintainers from some other projects) I strongly believe adversarial interop is a basic digital right that is required to fulfil the broken or revoked promises of web 2.0
If you know anybody that can help please let me know because I want to get back to maintaining the project.
Did you contact specific organizations such as FSF, EFF, etc and/or specialized lawyers? There were well known people defending itself or being plaintiffs. For example, https://cr.yp.to/export.html
Meta has done this before to insta and android devs.
Some never came back to their projects. It causes insane amount of stress and depression amongst the devs I've spoken with who went through the same thing.
