What does he mean when he says you're using his SnapChat filters?

If you're not familiar, snapchat has a neat advertising feature called "Geo Filters." The idea is that you're taken to a geographic location (like on Google Maps), and then are able to draw a bounding box around a certain area. Say I create one for my house that is within the bounds of my property. Anyone who comes on my property and turns on snapchat will be able to frame their photos with a special filter accessible only to those who were there in person, so maybe on for "RHL's Birthday" or something. They're popular at concerts and festivals, since only those who were physically there can get them.
I doubt there is any legal precedent for suing someone for putting their geo filter on a location where a competitor is working (technology is too new), but I can TOTALLY see why this guy is ticked. Imagine if the a Ferrari dealership put their Geo Filter over the Lamborghini dealership's location in town, so anyone who opened SnapChat there would see what is basically a competitor's ad, tied to their location.
I agree with other posters; other than the fact that I'm sure OP's business model, like all aggregators, involves skimming the profits of the trucks in exchange for leads/sales (sometimes that they wouldn't have made without you, sometimes not) to make money. This guy likely feels threatened because, as an organizer, that is basically his business model, albeit a slow-lane version.
But I'm not sure. OP needs to provide more detail.
