This is how the tobacco companies were able to refute connections to smoking and cancer for so long and probably why they weren't just shut down completely after losing court battle after court battle.
No. Just no.
The tobacco companies kept the law off them by running a FUD campaign of epic proportions.
They created and paid for think tanks to do research and write papers that refuted scientific fact.
They had an impressive lobbying organization that aggressively lobbied in Washington.
Books have been written about it based on everything that came out in court.
Once the Master Settlement Agreement was made, the tobacco lobbying and FUD money dried up.
The portions of the tobacco FUD machine that weren't dissolved, looked for other sources of income.
I'll leave it as an exercise for the reader to figure out who they're shilling for now.
