“App store” means a publicly available Internet website, software application, or other electronic service that distributes software applications from the owner or developer of a software application to the user of a mobile device.
This sounds like it could apply not only to F-Droid but also to any website distributing APKs, and actually, every other software distribution sysem too (eg, linux distros…) which include software which could be run on a “mobile device” (the definition of which also can be read as including a laptop).
otoh i think they might have made a mistake and left a loophole; all of the requirements seem to depend on an age verification “under Section 121.021” and Section 121.021 says:
When an individual in this state creates an account with an app store, the owner of the app store shall use a commercially reasonable method of verification to verify the individual’s age category
I’m not a lawyer but I don’t see how this imposes any requirements on “app stores” which simply don’t have any account mechanism to begin with :)

(Not to say that this isn’t still immediately super harmful for the majority of the people who get their apps from Google and Apple…)
