Is all Anvil client-side code de facto open source?

[ianb]

I think a better solution to the problem, though not the question you asked is simply this in your server code:

@ianb

the country location is also available if it is something you want / want to restrict, it is available through:
anvil.server.context.client.location.country
you could do a:

allowed_countries = ( 'United States',
                      'Ukraine',
                      'Latvia',
                      'Unknownistan',
                      'Elbonia',
                      'etc')
if not anvil.server.context.client.location.country in allowed_countries:
  anvil.users.logout() #  Or whatever stops them from using the App
  return False
