@TheDidek I saw that Pearcleaner's code is open source, so I'm not sure where the issue lies.

@jaywcjlove Look closer at the license:

Without limiting other conditions in the License, the grant of rights under the License will not include, and the License does not grant to you, the right to Sell the Software.

The source code is publicly available, but clause like that makes it proprietary, it is not Open Source by any recognizable definition.

Oh, I see. It should be replaced with a different icon, the one for "Source Available". @TheDidek
