Hi David M, you're not being difficult at all as it is a good and respectable question. I'll give an example right off the top of my head
. When one of the major car companies in the US came out with an electric
car "years" ago, not long after the great gas scare, then when agreements were reached, they demanded all of the cars back, with not compensation and literally smashed and destroyed them. They gave no explanation as to why.
There were also several free energy patent attempts but when it was time to demonstrate the equipment
, the patent office appointed engineers who were tasked to recreate the function, deliberately crossed wired and grounded the device so the output would be minimal.
The list goes on as you only need to do some research
of your own. I'm a retired engineer
myself and these events
are things that I have first hand knowledge of.
I can assure you that companies or subsidiaries of these companies purchase
what they can so it won't effect their overall dominance in whatever market they may have. Another example of this would be Microsoft. They have been dominate for as long as they have because of buying
up smaller companies and their technologies to either integrate into their suite of software
or to just squash.
You can choose any industry and this happens again and again.. But, I don't want to get off track here.
Hope this helps.. Also, I'm old enough and educated enough to never make a blanket remark without knowing enough about the subject to make that remark in the first place.
