Does anyone else think that Castle "opensourcing" essentially just the ROM apps (!Paint, !Draw etc.) is just their way to get the RO5 apps up to the spec of Select's apps, without paying for their development, and at the same time stopping ROL from benefitting either?
It's not as if their going to release the real meat of RISC OS (kernel, WIMP etc.) so that you could effectively compile your own RISC OS.
As for the Qt (not KDE) dual-licensing, it has for years been a bad bit of P.R. for Trolltech, until they finally gave in and released a GPL version of Qt4 for Windows last year, although it's still a bit cut-down (no XP styles, doesn't compile under VisualStudio etc.)
