While revealing Lore on your characters and or potential plot spoilers can be a concern. If your characters have places they do frequent business, or work at. Or say run a corporation or have a important corporation involved with your character. Those should be discussed, not in spoiler revealing detail, but the public front of them. Things any general citizen would know.

Bob Of Bobcorp is the CEO. Or Bobcorp produces tape. Things of that nature. If Bob produces secret weapons for the Government no one needs to know that. Unless you get around to covering it in IC  then why not add it into.your compiled Lore. 

We don't need any spoilers. But knowing who runs what, what they typically manufacturer and who they've been involved with will help us from having six tech corporations that do the same thing.

Plus we need to be careful when we could possibly restrict other character builds and backgrounds. Maybe having somethings already established new players can tell what's been done and who controls what should I for instance want a character with a Greek God as a patron.
