Opinons are like, well you know the rest. Just for info, I found this information on a public forum, used by 1000's of people. It was free to download,, the authors name is on the bottom of the last page. I can only guess that the author posted this information to be shared freely since he did post it on a public forum. There is also no reference to any company sponsorship in the writing of that document. There are references and credits to sources of information provided by other third parties. I do not know anything about the "Company" that you linked to, or as to where they obtained any information in any of their "plans" that they sell. Altho just a brief reading of their webpage seems to suggest that they gather free information provided by other non compensated individuals and then assemble that free information in a info package for resale. I can also understand the value of doing the research and being compensated for that research. these companies depend on people like you that either cant, wont, or are to lazy to do the research, and are willing to spend money to have someone do the work for them.
Now, I can understand how someone that doesnt know how to do something would ask questions. I cant understand how someone that paid for information on a subject, only to find out later the same information was available for free would want to Chastise the person providing the free information. You probably should instead be asking for a refund from the company that charged you for what was pretty much free and common knowledge. I regret that you wasted your money on your purchase. I equally regret that you felt it necessary to waste my time by having to respond to your baseless accusations
