Oh they're still very much astroturfing, @Anonymous! In Jersey City, just as one example, where there's a bitter battle taking place right now between the pro- and anti-Airbnb'ers ahead of a Nov 5 ballot initiative, the driving force behind the "Keep Our Homes" campaign is none other than ex-journo Graeme Zielinski, a former Wisconsin Democratic Party staffer who was removed as the party spokesman after a Twitter outburst in which he compared Republican gov. Scott Walker to serial killer and cannibal Jeffrey Dahmer! Apparently, that was just the straw that broke the camel's back tough... he had form...
Another figure who's been pulling a lot of strings in the Jersey City campaign is a guy called Mike McKay, real estate agent/investor and Operations Director for Howard Hotels, (with 17 STR properties in JC), and Airbnb "guru", who runs meetups in NYC on topics such as "How To Scale Your Airbnb business to 70+ units".
Also, critics have pointed out that the several key members of the Keep Our Homes campaign, including chairperson, Liz DeBold Fusco (also Airbnb's NorthEast Press Secretary), don't even live in Jersey City. Not very grassroots, in the traditional sense of the word!
I've followed all the JC council meetings online, and from what I could see, hosts aren't exactly turning out in their droves in support of Airbnb. The Jersey City Airbnb FB has negligible engagement from small local hosts, and it appears that only around a dozen turned up for the launch of the Keep Our Homes "Vote No" campaign last month. (There was a similar lack of engagement from regular hosts throughout the entire regulatory process here in Dublin, although there was no $3 million - or even $3! - fund ponied up by Airbnb to fight any campaign in this city, as there has been in JC)
So yeah, they're still astroturfing all the way.
