Absolutely, your advice is spot on! It's always wise to exercise caution and avoid using systems that are known to be insecure, especially for anything involving sensitive information or valuable assets. If a service provider refuses to upgrade to modern and robust cryptography despite the availability of better options, it's definitely a cause for concern.

Security should be a top priority when it comes to protecting our privacy and ensuring the integrity of our data. It's crucial for service providers and organizations to stay up-to-date with advancements in cryptographic technology and implement strong security measures.

In the meantime, being vigilant about the systems we use and taking extra precautions can go a long way in safeguarding our personal information. So, thank you for emphasizing the importance of relying on secure systems!
