If anyone at Opera is reading this:

Please open source Carakan and Presto - don't let them rot, and us hackers have what to learn with them (and potentially do with them). GPL is fine, and may let you still monetize it.

(And ... it's not like it's giving you any advantage - you've switched away from both)

From this presentation (http://vimeo.com/73934576): Presto don't go open source in the foreseeable future, cause Opera don't want to lose support contracts for the TV browsers. That's makes sense.

Would it not be possible to add some terms to the licence to protect that revenue stream in some way?

Restricting commercial use would disqualify it from being "open source" according to the OSI's definition [1]. If you changed the text of the GNU GPL, the license proposed by the GGP, you would also no longer be able to call it the GPL since the text of the license itself is copyrighted and not free to edit (to, e.g., prevent fragmentation) [2]. If you did all that the source release could well be a net negative for whatever goodwill the FOSS community has for your company.

What they could do instead is dual-license it under a strong copyleft license like the AGPL 3.0 and a proprietary license betting on companies being reluctant to share their source code. Still, it would hardly be to their advantage at all.

Edit: clarified how the GPL can be changed.

Opera Mini still uses Presto. It is quite popular still, especially where people can't get 3G or better coverage.

And I don't know anyone (from the few people I know that use Opera) who switched to the new Opera (since it sucks).

Is Carakan being used in anything other than older Desktop Operas?

Also Please, Release Opera 16 for Linux already. As a long time Opera user I feel completely abandoned.
