I know I'll probably catch flack for this, but I really disagree with what he did.
He broke into the Van Wagner advert boxes and replaced the contents. It's not like he stapled them to telephone poles, or somewhere else public notices are commonly posted.
Do I think the charges are overblown? Yes. I'd equate it more with trespass and vandalism, but I still don't think this is the Free Speech issue it would be if he'd posted them somewhere more socially acceptable.
I suggest you contact the film commissions of Louisiana, New Mexico and Georgia and ask how it's working for them. Tyler Perry Studios (Atlanta) alone employs several hundred GA residents. There's a studio complex in Peachtree City and a $100 million+ soundstage on the board for Atlanta and a smaller one slated for Savannah. The Georgia political/fiscal scene couldn't be more conservative. All signs point to you talking out of your ass.... again.
Are these temporary offsite or remote filming locations like what's going on in New Zealand, or are these permanent or semi-permanent operating facilities, ala Hollywood studios?
Just as dog owners are accountable for the actions of their dogs (in most jurisdictions) it isn't so far fetched (or even beyond legal precedent) to believe people will be held accountable for what their computers do with their ISPs.
Yep, and we should arrest all those folks who leave their wifi open for people to use, when someone else connects and does something illegal. They shouldn't do nice things for other people.
And anybody whose wifi gets cracked and the hackers do bad things. They should have secured it better.
And all those people who let their computers get compromised and end up in botnets doing attacks. They're practically cyberterrorists.
After all, it's their computer and their ISP. They're liable for it.
It's not computer fraud. The program did not break into their twitter accounts. It asked for permission to post (like almost every smartphone app these days, whether they need it or not) and the users gave it permission.
