This law is plain intrusive. The Indian players are standing up to it because they have the financial muscle to do so. The players from other countries have no means to stand up to WADA's bullying. So they sign up meekly.
This law may result in players from India, Pakistan, Sri Lanka or Bangladesh who are lax in following rules and regulations to be debarred for reasons other than to do with cricket or drugs. The Indian players most probably will end up hiring personal assistants who run around the players updating their schedules 24*7*365.
