Insane? This isn't me working at CVS or McDonald's and someone knocking off the cash register. This is an actual company that actually does important (at least in my mind) stuff.
LOL at shrugging and going about my day. Subscription fees help pay my wage, it paid for the equipment I use in a given day, the computer that sits on my desk, etc. Yeah, the NBA might be asleep at the wheel here but it wouldn't be us. That shit does cut into your bottom line at some point.
If you got paid directly from subscription fees, and someone was skirting the subscription fee of your service and in turn offering it to others on the internet for a monetary fee, I highly doubt you would just shrug and go about your day.
There are no such sites that I know of, since our legal team actually does their job, apparently unlike our counterparts at the NBA if this thing lasted all of last season. I have never seen an MLB stream even listed on the handful of sites I stream soccer or basketball games from, and if they do ever hit the site we have people who monitor that shit and take them down.
Allowing people to use your product for free is bad for business, but going even further, allowing someone to steal your product and then sell it to hundreds or even thousands of other people is really bad for business.
If this guy was just running his own free streaming service like firstrow or atdhe that'd be one thing, but he's charging people money for a service he doesn't own the rights to. That's the definition of copyright infringement and I'll be shocked if he isn't popped for it.
