Perhaps this is why OSI is useless and FSF useful despite the oddities of RMS, it's the same "software you can look at but not touch" all over again.
Sorry, stinking load of crap. Even when somebody takes some BSD-licensed code and does nifty magic with it under a proprietary license, the BSD-licensed code they started from remains available to you. So, no "software you can look at but not touch". If someone takes some reciprocal licensed code, and does nifty magic with it, they have to release it with the full rights they had. So, no "software you can look at but not touch".
It's the enemies of freedom, the enemies of openness, that claim that open source code is "code under glass". If it's open source, you can get the source, period. If it's open source, you can modify it, period. If it's open source, you can share it, period. There might be constraints on sharing, like the GPL's requirement that you share source whenever you share binaries, or the QPL's requirement that you distribute modifications as pristine source plus patches.
