What part of wefwef would cause an issue? Unless the wefwef devs are using visual assets from Apollo that are not free to use, there's no issue.
You can't sue someone for... What? The visual placement of buttons? How the animations work? The entire software industry would collapse overnight if we couldn't re-use design patterns.
I didn’t mean it as a bad thing, I’m extremely fond of the design, it’s almost identical to Apollo and didn’t know if it would become an issue in the future because of that, that’s all I’m asking.
