When I explain situations I've encountered in the past, I make some small tweaks.
- Name and Gender - I pick a random name from a random name generator, and then use the appropriate gender. I don't want to bring in any unintentional bias regarding gender or ethnicity.
- Project description - If there's any reason I believe that it is unwise to identify a specific department or product, I will change a critical identifying detail to avoid identifying things specifically.
- Wording - Most of my wording, from email or discussions is based on my best memory, not specifically copied. The only exception is if I'm referring to newsletter communications from current readers.
