You have a similar problem with police. If you day to day see instances of crime and you have a lot of contact with criminals, you develop preconceptions towards people. You view gets skewed and you start to see crime everywhere. The same happens to security agencies that deal day to day with the spy game. This is why external observers are necessary. Not primarily to punish people stepping over lines, but to provide support and reasonable boundaries and context. People with a strong sense of duty are especially vulnerable to develop a wrong perspective.

Then there is the other dimension where corporations just help the worst dictators for profit or provide surveillance capability against the population. Almost all major names in tech are guilty here to certain degrees. Some more than others, but there are no morals in business. Especially not with investment mechanisms like ESG or similar constructs to provide wellness to rich investors, but that is another topic.
