It's complete horseshit because public toilets contribute a statistically insignificant amount of sewage to the sewage system. And it is horseshit not bullshit because the people offering it care that people like you buy it. If it was bullshit, they wouldn't actually care if people like you buy it. And it has to be horseshit because unaffected people aren't going to buy into the idea of toilets having poor toilet paper just to make using them suck.
