You can make any move seem reasonable if you make a sufficiently bad analogy.

A more comparable analogy would be one where the hypothetical security company isn't told who of their staff is banned, or for what reason they were banned. Maybe they were a bank robber, or maybe they were just doing business with bitcoin, and it's the bank's policy to ban all such businesses. And the security company isn't just not hired - they're banned from being hired ever again, from 88% of all banks in the world.
