@joncampbell123 et al. (you prolly know this, but for the reference)
AFAIK, California's has AB 1856 now
https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202520260AB1856 :
(g) (1) “Operating system provider” means a person or entity that develops, licenses, or controls the operating system software on a computer, mobile device, or any other general-purpose computing device.
(2) “Operating system provider” does not mean a person or entity that distributes an operating system or application under license terms that permit a recipient to copy, redistribute, and modify the software.
Since DOSBox-X is OSS, the law now doesn't apply because providing OSS doesn't make you an "OS provider" now.
Likewise, SB26-051 in Colorado doesn't apply (explicit OSS exemption).
But, unfortunately, Illinois's HB5511 does.
This whack-a-mole is absurd.
