I was thinking this mostly from the standpoint of viral nature of GPL-kind of FOSS licenses. E.g. somehow, somewhere someone manages to inject a GPL licensed IP block into a commercial CPU, after which, with my layman understanding, chip manufacturer now owes under the terms of GPL everyone who happens to have purchased one of those chips a full VHDL, Verilog etc. source code of the entire chip.

In software you can always replace a library that had incompatible license with another. Not sure how this would work with a chip.

As for attempts to modernize EDA industry, I welcome that in open arms. And if in the process we end up open sourcing a lot of current IP blocks (think of USB, HDMI, etc. designs) - all the better.
