Oof, that doesn't sound like a popular move! Speaking of simulations though, there is SideFX Houdini? (can probably handle CAD-type stuff a bit nowadays? and certainly lots of types of simulations!)
I do hope that SideFX (Houdini) stays independent. Things I've heard suggest that they intend to, and I also hope that they continue on their current trajectory - I think the general direction is very positive! Not perfect of course (and not opensource of course, but very open in practice) A lot of very solid dev seems to happen at SideFX, and a lot is communicated about what's happening, and their support (email contact for when things go wrong) is absolutely STELLAR too!
