IMHO the "don't remove anything with a licensekey ever" part in the license is the kind of potential poison that I would never recommend this to my or any other company. More than a few fellow engineers consider nagware an insult and see the potential to twist your arm late in the game making former free functions part of a new "optimized pay package", which you need because you can't fix the bug in the goddamn license part that is a security risk. LOL. (Not saying that you ever do. See below)

And there is no moat, debugging AI flows is a few prompts and a claude code max, google gemini pro or codex whatever for a couple of days while doing the usual things will happen.

Note: Its not about this software specific. I learned that the cuts and bruises of incidents before you come along are the ones that shape behaviour of your partners/colleagues/peers. You may have the purest intentions and best approaches, but someone longe before you ruined it. Its not you, its you chosing the same path.
