(Again, I'm not saying Meebo is bad for doing this, I'd do exactly the same).
Lets suppose you reverse engineered skype. Would you open source it? Or seek to make at least a little money from it. If you chose to open source, it's likely many others would make money from it instead of you.
Here's what I think: the $200MM going to Meebo has NOTHING to do with them using the libpurple library. My reasoning: Any other web based chat company would have the same capability to exploit libpurple in their strategy. Web companies don't get funding for their technology ever. They get funding for their eyeballs and stickiness.
Finally, on the subject of backhanded insults: Imagine that you were physically speaking with a group of libpurple developers and said, "Boy, if I were in your shoes, I'd feel like a bunch of idiots!"
Without the libpurple library, Meebo may not have existed. Or at least would have been far far harder to execute afaics. libpurple isn't just another framework, or webserver. It's very valuable reverse engineering effort.
As I said, [I] would feel like a complete idiot, if I worked my ass off to create something, only to see a company exploit+monetize it. That is not in any way the same as calling libpurple developers idiots.
>> "How on earth would I make money from reverse engineered Skype? I can't even fathom it, the amount of work it would take TO make money from a reverse engineered protocol for communicating with Skype servers. I would not even know where to start."
Seriously?? There are many many ways you could monetize the ability to communicate over the skype protocol. You could build cool plugin services. You could build something to make peoples voices sound like robots - disguizr.com or b2b stuff, voicemail, you could build your own skypeout competitor. etc etc etc you could build conferencing services ontop of it. Prank/joke call things. Voice recognition bot services. I'd say at least one of those would work. If you sat down and thought, I'm sure anyone here could come up with some killer applications.
Some people can live with making enough money to have a pretty good life and not worrying about maximizing their revenue streams while just being happy that their work has meaning to others.
