No worries, I can see how it sounded. The project sounds pretty cool. I really dig the 90's UI of SerenityOS. Do you think the OS can be more than a novelty? I read that it doesn't support 3rd party software. Maybe I don't fully understand what that means, but wouldn't it mean anything that doesn't ship with the OS likely wont work? That I couldn't make my own package that could be installed via the package manager? Seems like that kind of OS just couldn't satisfy people's computing needs.
Not sure what your source for ”doesn’t support 3rd party software” is, so it’s unclear what that actually means, but there are numerous examples on Andreas’ YouTube channel about porting software to Serenity, e.g. Diablo [1].
Maybe the text you read refers to the OS itself and all first party software being written without external dependencies?
