I do believe they have tried to suppress it as much as they can but suppressing an idea is extremely difficult to do long term.
Also, people often wildly underestimate how long it takes for adoption curves play out, especially those that require network effects.
Electricity, Telephones and Automobiles all had roughly 1% adoption for the first 20 years before exploding upwards over the next few decades after their invention. Now it's difficult to imagine what life was even like without those things.
I mean just think about that... 2 decades for the first 1% adoption followed by 4 decades to get to 90% adoption.
