I understand your problem. I used to do family research on the web and there were a number of sites that had good information, then, Ancestry came along and realized they could charge an annual fee to those doing research. It allowed them to buy all the free sites so now when you do research you think you are on to something and the trail leads to Ancestry asking for money. Glad I did 7 generations back before Ancestry took over.
The same thing happens when you post about an adapter for a T-5 transmission and someone comes along and starts charging for the same information.
We have to be careful about complaining too much. It could allow Government to come in to "fix" the problem and regulate the Internet. We all know what happens when the government gets involved, we lose some of our freedom.
