For background -- and I am not an expert here -- their C++ frontend is widely known. I first heard of it because Visual C++'s Intellisense uses it, which was notable because VC does not use the msvc frontend for its own completion. I understand it's been either used or evaluated for other frontends in the past too. I worked as PM for one C++ product, and was fortunate to be able to learn a lot from our engineers; we didn't use it, but they thought highly of EDG.
It has a very strong reputation for being correct. And as such, I think open sourcing it will be a very beneficial thing for the C++ community.
There are essentially four C++ frontends: gcc, clang, MSVC, and EDG. Pretty much every C++ compiler is a reskinned version of one of those compilers. Most of the proprietary compilers have been slinking away from using EDG to using clang (e.g., Intel did this transition a few years ago).
The reason why the EDG frontend is being open-sourced is because EDG itself is closing up shop, and the open sourcing is an interim solution as EDG's customers work on migrating to using Clang instead. So... it's really not good news, because it means that one of the frontends is basically reaching end-of-life.
Where would that new life come from? As far as I am aware, there isn't exactly a thriving community around it which has been begging for a source release for ages, and with Clang and GCC there hasn't been a shortage of open-source C++ compilers either. And it's not exactly like the C++ ecosystem as a whole is booming, with it not having any answer to the memory safety problem.
From what I can tell this is just some retiring guys who want to make sure their life's work isn't lost to history, and who want to avoid screwing over their handful of remaining customers. Realistically, the best you can hope for is probably the occasional bugfix, and other open-source compilers scavenging it for a handful of useful clever ideas.
This. Maintaining a C++ front end is a lot of hard work that requires expertise -- I wouldn't be surprised if there are a bunch of CS PhDs in the team. You don't just randomly hire someone to work on compilers like with web development. I seriously doubt there will be a lot of contributions coming from the community. Maybe bug fixes, but likely not keeping up with C++ standards.
