One way for the big companies to stall adoption of FF by smaller entities is through tough regulations.
There is an interesting example of this in the US. The conversion of vehicles to run on natural gas is extremely expensive because of the high cost for a mechanic to obtain a license (apparently $200,000 per engine type per year).
So there is going to be intense lobbying for and against crippling regulations, depending on which side you are on.
On the other hand, it’s a global economy. If FF turns out to deliver cheap energy countries that adopt it without significant restrictions will enjoy an advantage. Governments in countries with severe restriction will face intense pressure from consumers and some industries to reduce regulations to ‘reasonable’ levels.
One possible outcome as Rematog maintained all along is that, at least initially, FF will be installed mostly in large facilities (i.e. retrofitted power plants and large industrial plants that need lots of power). In these places the overhead to comply with regulations is relatively low.
