One of the benefits of Bitcoin, and other cryptocurrencies, is that it is meant to be a peer-to-peer network meaning that no central authority or third party is needed to transact. This news from India only makes it more difficult to access fiat to crypto exchange when using banks. However, as you state it does not outlaw the use of the assets. Therefore, users can potentially get access to Cryptos with directly purchases from other holders or cross borders. Once you have it, it is very difficult for any one organization to stop you from using it given the peer-to-peer functionality.
