 [The Federalist] Between May 2018 and August 2019, the intelligence community secretly eliminated a requirement that whistleblowers provide direct, first-hand knowledge of alleged wrongdoings. This raises questions about the intelligence community’s behavior regarding the August submission of a whistleblower complaint against President Donald Trump. The new complaint document no longer requires potential whistleblowers who wish to have their concerns expedited to Congress to have direct, first-hand knowledge of the alleged wrongdoing that they are reporting.
The brand new version of the whistleblower complaint form, which was not made public until after the transcript of Trump’s July 25 phone call with the Ukrainian president Volodymyr Zelensky and the complaint addressed to Congress were made public, eliminates the first-hand knowledge requirement and allows employees to file whistleblower complaints even if they have zero direct knowledge of underlying evidence and only “heard about [wrongdoing] from others.”
The internal properties of the newly revised “Disclosure of Urgent Concern” form, which the intelligence community inspector general (ICIG) requires to be submitted under the Intelligence Community Whistleblower Protection Act (ICWPA), show that the document was uploaded on September 24, 2019, at 4:25 p.m., just days before the anti-Trump complaint was declassified and released to the public. The markings on the document state that it was revised in August 2019, but no specific date of revision is disclosed.
The complaint alleges that President Donald Trump broke the law during a phone call with the Ukrainian president. In his complaint, which was dated August 12, 2019, the complainant acknowledged he was “not a direct witness” to the wrongdoing he claims Trump committed.
A previous version of the whistleblower complaint document, which the ICIG and DNI until recently provided to potential whistleblowers, declared that any complaint must contain only first-hand knowledge of alleged wrongdoing and that complaints that provide only hearsay, rumor, or gossip would be rejected.
“The [Intelligence Community Inspector General] cannot transmit information via the ICPWA based on an employee’s second-hand knowledge of wrongdoing,” the previous form stated under the bolded heading “FIRST-HAND INFORMATION REQUIRED.” “This includes information received from another person, such as when an employee informs you that he/she witnessed some type of wrongdoing.”
“If you think that wrongdoing took place, but can provide nothing more than second-hand or unsubstantiated assertions, [the Intelligence Community Inspector General] will not be able to process the complaint or information for submission as an ICWPA,” the form concluded.
Markings on the previous version of the Disclosure of Urgent Concern form show that it was formally approved on May 24, 2018. Here is that original Disclosure of Urgent Concern form prior to the August 2019 revision:

Ref #5: I'm going to make a wild guess and say the people behind the green door both changed the rules and were the "whistle-blower".
