So why is Picasa not Free Software?
This might come as a shock to you, but Google is unfair.
Yeah, a real shock.
They're using GNU/Linux heavily. They even have an in-house version of Ubuntu, but when they release software it is proprietary. Why, exactly, is Picasa non-free for example? What do they get out of it? It is free of charge anyway. May it be the precious algorithms they use in the code? Yeah right. And so what if they feel they have trade secrets in there. It is still unfair. GNU/Linux has plenty of cool code in it and it is still successful. I would dare to say that Picasa would be even more popular if it was Free Software!
No, Google is not just unfair. They're really stupid sometimes.
