I'd hate to disrupt this thread once again, but wouldn't it make a major shift in the whole of Linux and the community if the creator made it available to everyone and provide source code? I like the developer's perspective of making things easier, and making TUI and complicated applications into an easy to use and understand GUI interface.
Every week (or even day) there's always some new software. However it doesn't benefit Linux or most users (not saying it should benefit, but just saying) and most of the software is always some new terminal program or some small fun tool.
The creator should also consider making their software open-source. Again, I don't want to disrupt this thread, and I know what @root talked about the "Dark Web Linux Mafia Gang" but I disagree with what the creator said about making software open source.
“They want you to release your Proprietary Code as FOSS in order to profit from it.”
Honestly I don't know how would one profit from making the code open source.
“It's a classic tactic of the Linux Mafia Army, to apply negative psychological pressure in order to discredit and discourage developers, steal their code and profit from it in any way.”
I think this never really happen, but one prime example is nVidia and Valve:
nVidia drivers are terrible on Linux, due to the neglect of nVidia. I have seen many "cursing" on nVidia, getting them to make the drivers open-source and even a hacker that threatened nvidia to hack them, unless they make the drivers open source. The hacker (Lap$us) got arrested.
Basically, if nVidia made their drivers open source, with community contributions, they can be better on Linux, and possibly as good as the driver on Windows. Currently, the open source nvidia driver is better than the proprietary one right now.
About Valve:
Valve is the company behind Steam, the popular game store and manager on PC. It's where most games are on.
Recently Valve (Gabe Newell, the founder) has seen that Linux can be a viable gaming platform, and he is doing everything to make it better. The Linux Community (almost everywhere) likes Valve for their efforts for revitalising Linux gaming. However, Steam is not open source, however no one complains about it.
It's biased but I guess that's how it is.
There's also Snap, which many users particularly don't like and Ubuntu has been going downhill just because the Snap Store is not open source....
Thanks for reading. Have a good day.
