Red Hat entirely operates on a business-licensed version of a fundamentally free product. Oracle does pretty much the same. Many large, widely deployed and lucrative software packages are completely open-source. Because there's very few businesses who think that grabbing those packages without vendor support is a good idea. Especially in the EDA industry, with its very sensitive and particular cores, having the source does not guarantee it working, let alone working well. Buying vendor support is cheaper than winging it yourself. I guarantee you, every single Chinese manufacturer who wants to dodge licensing fees has already done so with stolen IP cores. After all, EDA companies are hopelessly stuck in the past and woefully unaware of proper security practices.
