Christopher Snowdon reported the details of the story back in February. He wrote:

2. "Remember the National Smokers Alliance, Philip Morris' phony grassroots network? How about all those "studies" looking at public support for or economic impact of smokefree laws? They're back: There are three national e-cigarette "trade associations" one of which, Smoke Free Air Trade Association (SFATA), has several board members with ties to Big Tobacco. Also, two new statewide front groups, Oklahoma Vapors Advocacy League (OVAL) and Iowans for Alternatives to Smoking and Tobacco (IAST), have popped up and are providing testimony in favor of e-cigarette use. A lobbyist for IAST has also lobbied for Philip Morris."
If this study leads some smokers to smoke inside because they believe the researchers, who say that thirdhand smoke is no less harmful than secondhand smoke, then this could lead to serious public health harm to children.
According to an at CSPnet.com: "The nation's tobacco companies and the U.S. Department of Justice (DOJ) have reached an agreement on publishing corrective statements that say the companies lied about the dangers of smoking and requires them to disclose smoking's health effects, said an Associated Press report."
The beauty of a randomized study is that it can equalize the levels of smoking addiction, reasons for wanting to quit, and motivation to quit across groups. In addition, it equalizes other confounders, including unknown confounders which could affect the study results. There is no way for a survey study to accomplish this. Thus, to simply throw out the RCT is quite unscientific, in my opinion. It throws out one of the most valid pieces of evidence that is necessary to make an informed judgment about the effect of these products: the differences in effectiveness of the products under conditions in which confounding cannot throw off the results.
