@InitiatedAunt74,
I would agree that it doesn't seem Gizmo would be for you on the premise that you prefer a per-aircraft setup. Linux is up in the air as well, and as you've indicated that's important for you.
For now, we really aren't utilizing it for anything but payware. That may change one day, but not for now. I won't get into semantics over your displeasure with Ben, but I will stand up for Gizmo and state that it's extremely powerful and optimized over the competing option.
Only other note, while irrelevant at this point, is Gizmo is installed already on hundreds of thousands of computers. The per aircraft thing is kind of moot anyhow at this point. Chances are very, very slim someone you have installing whatever future product you create doesn't also have Gizmo installed anyhow.
Best of luck in whatever you create!
