Aside from what was already mentioned in another comment, one of the largest things lacking in this area is not having dedicated support. These tools are maintained by only a few individuals, and if you need a feature of bug fix, you either need to implement it yourself or wait a long time for a fix. If you need a feature or bug fix from Cadence, Synopsys, or Mentor, I've usually had releases that fix the issue within a week or two. The article seems to imply that EDA vendors contributing to a common open source project is where EDA ought to go moving forward. That's a step in the right direction because it'd fix this support issue I mention. But it probably won't fix the cost issue.
