Doesn't seem to have stopped Symbiflow from supporting Xilinx-7 parts. https://symbiflow.github.io/ https://symbiflow.github.io/

  Who Xilinx choose to set their lawyers on is up to Xilinx. They promised to clam down and update their policies after the education video takedown blew up in their face back in January, but they have yet to do update their policies so as far as I can see from their legal page (which is where they said they would post the updated policy). As the saying goes. Once bitten, twice shy.

    I think you have an excellent point. Why bother with a company if they sick their lawyers on hobbyists and experimenters? With CPU's the modern software engineer expects a new GCC/LLVM target, so we can have a consistent experience with one code base. I get that. I believe the market is shifting under the FPGA's faster than they realize. Sure they're going to have large corporate customers for a while using the xilinx proprietary IP cores, etc. But someone at some company is going to get a bonus for saving the company tons of money by modifying an open source core, so they can drop the cost of using the xilinx proprietary cores.

It's not quite ready yet, but the Orangecrab looks really exciting- 85K LUTs, all IO broken out, feather form factor, 8gb RAM, Lipo connector, open source toolchain. There are enough gates to do some interesting stuff without it getting overwhelming, and you can run a RiscV softcore. https://www.cnx-software.com/2019/08/28/orangecrab-is-an-open-source-hardware-feather-compatible-lattice-ecp5-fpga-board/ https://www.cnx-software.com/2019/08/28/orangecrab-is-an-ope...

I looked at the DCMA takedowns and they were all for either license files, or encryption keys. I'm not sure what you expect a company that sells software to do in these circumstances. This very different from the sort of reverse engineering that e.g. project X-Ray is doing.
