Your plugin is used in proprietary software CENOS

[jwcrawley]

Greetings,

This isn't about any bug or documentation. This is about some new proprietary software called CENOS (Connecting ENgineering Open Source) that's used to calculate radio propagation in antennas, to help create new shapes and tuning antennas.

Normally, this project is about importing Autodesk Inventor files into FreeCAD (I love me some fFCSTD!), which is kickass! HOWEVER....

CENOS has included your plugin in its entirety in the binary closed source package here: https://www.cenos-platform.com/antenna-design

In the location cenos-antennas-setup.exe/$PLUGINSDIR/app-64.7z/backend/app/freecad/freecad/InventorLoader-master/ is a complete copy of your software. Worse yet, CENOS has decided that using your GPL2 plugin is only for "Professional" licenses at $99/month. ( https://www.cenos-platform.com/ad-pricing-euro )

I've already mentioned this on Twitter https://twitter.com/CrankyLinuxUser/status/1395448693424332801 On reddit: https://www.reddit.com/r/rfelectronics/comments/ngvzaj/lowcost_antenna_simulation_software_launched/ And as an email to HackADay.

I also know that they use a whole lot other LGPL content, provided as a binary only. We have no clue if they've modified them or not - If they have modified, they're also in breach of those licenses.

I thought you should be made aware of this.

Sincerely, Josh Conway
