There is no conspiracy. It's a standard industry transform/consolidate play. From a public health perspective, a $1 McDonald's burger made of coconuts/pea/soy/salt is just as bad as the incumbent beef-based product. The capital behind meat alternatives does not give a hoot about animal welfare or anything beyond money... meat alternatives are the new Coke.

It is much cheaper to operate a couple of large national-scale factories to produce plant-based meat alternatives with mostly automated equipment and minimal regulatory oversight. Meat processing either needs to be regional, which is higher cost, or national, where limitations or capital costs of automation require a large pool of unskilled labor. You "fix" factory farming by enforcing labor standards at the processing layer that make concentrated, high throughput meat processing uneconomic. The result would be changes in how the industry functions and higher prices. (ie. market forces)

Those same market forces would ultimately drive more plant-based calories in diets and probably healthier eating habits. Factory farms exist because USDA policy since the 70s have been focused on slowing inflation in food prices. That policy ultimately drives alot of unsustainable practices, from factory farms for livestock, to the long-term depletion of the Ogallala Aquifer, to the transfer of topsoil from the Mississippi/Missouri/Ohio river watershed to the Gulf of Mexico. 50-100 years from now, our descendants will be returning to regional agriculture at very high cost as midwest production fails and climate change breaks the environment the supports the magnificent bounty of the California central valley and Colorado watershed.
