Interesting range of reactions to DraftSight running on Linux:
There are 92 comments as I post this. Some readers complain it isn't open source, as Linux users expect. Others complain it isn't fully 3D. But kaka.mala.vachva responds:
You realize stuff like this is the only way Linux may become popular on the desktop? We can't really expect everything to be FOSS [free and open source software]. Support this if it's useful to you, and look past the activation -- more companies may start developing for Linux then. Would hate to see the Loki* story all over again.
*) Loki failed in its attempt to port games from Windows to Linux.
