Although I agree with you they're unquestionably not half assed fans. I've been attending races with 2 of them for 20 years. They still attend races of all persuasions from Daytona and Indy to Fairbury, La Salle and Eldora.
I do, however, believe at this point the number of people who are engaged in the Facebook Live and Periscope culture are relatively few.
Frankly I am somewhat surprised that there hasn't been an effort made by track owners and promoters to put a stop to what's going on. If in my little world I know of 2 or 3 who forego attending events for watching it for free I'm sure these guys aren't isolated cases and there are more all over the country. Even if it's only one the promoter/promoters are losing money.
