You seem to be under the impression that Dolphin is licensed under the GNU General Public License, or similar. While this was the case in the very early days, it's no longer the case now. I personally wouldn't support an operation like this, as it deprives the real (I can't emphasize this enough) developers of the needed income to continue their work.

I don't understand why people continue to think open-source is the equivalent of being in the public domain--it isn't. I can release my software see more as open-source, but still bind it to a license that forbids certain actions, and that license must be followed to the letter, where legally applicable.

Dolphin is licensed under the Creative Commons Attribution 3.0 license. This means you are able to redistribute and adapt the software to your needs, under the condition that you provide attribution to the owner of the original work, as specified. In this case, attribution means the links which can be removed by paying for and applying a license.

In short, what you're attempted to do violates the license of which this software is distributed under. Even if that was not the case, the thought of depriving the developers of their much needed income over a link, which is non-obtrusive and fairly inexpensive compared to other licenses for other software on the market, is something to be ashamed of.
