Why no paid plan yet?
The current installer does not include license enforcement, and the first release is intentionally unsigned while compatibility is validated. Keeping the pilot free avoids promising paid gating that the software does not yet enforce.
After enough real-world testing, paid licensing may be introduced with clearer release quality, signing and support expectations.
