Eh, yes and no. I would say there is a large (probably majority) of marketers who are old school, and are like you say. They buy TV and billboards and (in Triathlon case) magazine ads and they create complicated tracking metrics to 'prove' they work and sometimes they do....most times they don't (you ever seen an MMA/MMM report? barf). Then there is a new school (which is my profession) which looks at search (Google/Bing), Social (Facebook/Insta/Snap/Twitter), video (Youtube) and other display areas and they use much better data to 'prove' they work.
For example, if the people at Hot Shot are worth a sh!t I am sure they have Google Analytics (or similar) running on that ad and if/when you click on it they cookie you. Then they track you and see when/if you convert. Do you buy product now, do you sign up for email, do you go to the info page and spend 3 min reading about the product and what info can they pull from that experience. Then if you don't buy they are retargeting you across any channel they can get their hands on (I am guessing this is what Roka does this with display ads), they might feed you facebook ads, they might bid to the top position if you Google [how to cure dehydration], they might target you with a :15 video on Youtube, anything they can do to get back in front of you since you raised your hand and said 'i'm kinda interested in this product' by clicking on that ad. In the end, they hopefully have an idea of what the purchase journey is for their product, how long it takes, how many times they have to touch them before they convert, what channels convert best, what demographics convert best etc etc etc and the more they do this the better and better their data become and the cheaper and cheaper their advertising becomes.
Shameless Plug: Hot Shot - if you read that and have no idea what I am talking about....DM me and we can talk ;-)
When it comes to you as a liability, that's on you, but I would say as a general rule of thumb "compliment publicly, criticize privately".
