Religious charlatans have been doing this by publishing literature and selling them to the public going right back to the 1800's, disregarding Jesus's own instructions for preaching his gospel in the process.

“You Received Free, Give Free''
Watchtower 2003 8/1 pages 20-22
By way of contrast, Jehovah’s Witnesses endeavor to imitate Jesus and his early disciples. They have no paid clergy. Each Witness is a minister charged with the responsibility of preaching the “good news of the kingdom” to others. (Matthew 24:14) Over six million of them worldwide are therefore engaged in bringing “life’s water” free to the people. (Revelation 22:17) In this way, even those who “have no money” can benefit from the Bible’s message. (Isaiah 55:1) Although their worldwide work is funded by voluntary donations, they never solicit money. As true ministers of God, they are not “peddlers of the word of God,” but they speak “out of sincerity, yes, as sent from God.” —2 Corinthians 2:17.
Really? The WTBTS is the biggest ''peddler of the word of God.''
How many books, Watchtower & Awake Magazines subscriptions were either sold to its members or the general public? How many 180-page books were printed? How many times were we reminded in ''Our Ministry School'' to try to place these books 180-page (where the general public would never understand or have no interest in reading?) Were these books collecting dust in a warehouse and needed to be cleared out? Someone had to pay for the printing of these books!
Hypothetically thinking, how would Jesus react or do if he saw his apostles selling his Gospel on the streets to where he preached and traveled about. ?
Today, if Jesus ( if he was real ) would walk into a local Kingdom Hall library and throw all books off the shelf. Most of these books are ''old light'' anyway.
