Well, there could be a few reasons why someone might design something to be easily compromised. One possibility is that they prioritize convenience or ease of use over security. For example, a company might design a product to be easy to set up and use without requiring a lot of technical knowledge, but in doing so, they might sacrifice some security measures that would make the product harder to compromise.
Another possibility is that the designers simply didn't anticipate all of the ways that their product could be compromised. It's difficult to predict all of the potential vulnerabilities that could be exploited by hackers, and sometimes even seemingly small oversights can lead to major security breaches.
Finally, there's the possibility that the designers intentionally designed the product to be easily compromised for nefarious purposes, such as to gather user data or to allow for remote access to a system. However, this is a less common scenario and would likely be illegal.
