You know, I've been wandering about this. I've noticed that the gurus are almost always willing to share their knowledge. They don't try to hide anything. Why? The conclusion I came up with is that while the skill is transferable, the talent never is. I think this applies to any endeavor - trading, computers, medicine, etc.
Every talented person or organization has secrets, or proprietary data/information.
They may be willing to freely share 'old' secrets, but not recent secrets that took a lot of talent, time, money, and/or other valuable resources to squire, imo.
Old governmental top secrets and classified technologies become public domain when they become obsolete
to the government. You can replace the word 'government' in the prior sentence with any 'individual' or 'organization.'
It is also
possible that an individual or organization may drop additional bread crumbs into the public domain with the hopes that it'll keep others, i.e. the competition, wondering around in the rabbit hole for a longer period of time--especially if they see that someone or some organization is 'on the right track.'
For simple example, there may be public discourse about the effectiveness of the EMA5. An individual or organization may have recently discovered that the EMA6 beats all other indicators. So, that individual or organization may decide to "help" out the public, or academia, or individuals in chat forums, that seem to be on the right track by revealing that they (the individual or organization) discovered (long ago) that the SMA4 beats the EMA5!
They may do this with the hope that attention will be diverted away from EMA's all together.
This is a very simple and unrealistic example, but hopefully the point is clear.
Everyone then wants to be their friend, calls them guru, and publicly appreciates their contribution to the discussion.
Just a scenario to be aware of ... FWIW
