You had my interest until "source available". Especially when you used MIT from the start and changed it later. FOSS hackers like me feel betrayed by moves like that. Also I for one would never invest a second in tools I cannot freely modify and share the code of. I would strongly suggest a convenience tax model. Hackers will self host and maybe contribute but those with more money than time will put in a credit card. Maybe offer end to end encrypted memory and compute to secure enclaves where additional compute on the data can be done when the laptop is closed.

However, with "source available" you are just begging for someone to AI launder your code into an OSI clone you will have 0 recourse on, but if you OSI it yourself then you get to capture the community. Some of that community will have bosses that will pay you.

AGPL is a good middle ground as it flips the script. Corpos are allergic to AGPL and will pay for an alternative license, but for community hackers that might want to improve and recommend your code it offers no restrictions.
