To have access to something commercial for free may be nice.
The ideals of free software though call to produce free and open code because it remains free, open, and available. Siemens, were it to graciously offer some free tier access, would be also in a position to limit or withdraw such access at any moment. (This even applies to the paid licenses.)
However limited OpenCascade is, it's here, and it's usable, up to a point. I hope that a successor to it will emerge, if there's a need.
