CompanyA sells a product that claims it contains magic. You find it has none, you sue them for false advertising. Company has to pay you for court costs, loss of wealth in purchasing their good, and damages if any exist. CompanyA can go bankrupt in the process, and perhaps you end up owning CompanyA when all is said and done.
CompanyB sees that CompanyA did wrong, and suffered consequences for their actions. CompanyB advertises a product without magic, but instead what the product actually contains. CompanyB stays in business, and people buy their products as needed. Wow! We have just described a basic fundamental of Capitalism and how Western Law works! No need for the Department of Magic in Products which reduces the overall costs for goods. People can actually purchase _more_ of CompanyB's stuff and CompanyB can actually make more stuff, or even branch out into CompanyC.
I don't know if you're trolling or not, to expect that your average consumer is going to sue "CompanyA" over a $5 tube of aloe vera gel and somehow wind up owning said company. I couldn't convince a smart 12-year-old of that actually happening in the real world.
While your example sounds great in theory, here's what happens all too often in the real world:
CompanyA sells a product that claims it contains magic. You find it has none, but don't do anything because it is impossible for the average consumer to finance a lawsuit by themselves, and class-action lawsuits are extremely rare with a miniscule payout to everybody but the lawyers. Knowing this, 99.99% of the time people just shrug and move on with their lives. CompanyA may or may not have to pay some nominal fine which doesn't come close to the money they made through their lies.
CompanyB sees CompanyA make lots of profit and get away with it, and decides that they want a seat at the table.
And how do we know that that last part happens? Because if you had bothered to read even the summary, you would have seen that that is what actually happened.
I find it ironic that you are the one making snarky comments about cognitive dissonance.
