Agreed. If this were really about tortious interference -- if it had anything to do with principles or right vs. wrong -- they'd be suing every tabloid that's ever paid contestants for inside/confidential information. This is nothing more than the financial bullying of a small-but-annoying target, at very little cost to themselves.
This lawsuit is about one thing only. It's about shutting down RS. It isn't about getting a judgment against RS, it's about making it so expensive that he will have to desist. Secondarily, they would like to know his sources.
I have a dim view of wealthy entities who seek to limit those with fewer financial resources from ordinary activities that in essence do not hurt the suing party in any material manner.
I find RS to be a poor writer with bad grammar and a tendency to blow his own horn too long and too loudly. I could easily live without his blog and his spoilers. But boy, do I hate hate hate the thought that he could be financially screwed, and that his right to publish spoilers could be shut down, just because Fleiss and Co have bigger wallets. And all the while, the larger, less-easily-bullied entities (e.g., TMZ) carry on at will.
Not to mention that RS denies ever having offered money to anyone for information. We don't even know if the allegations are true. Whom to believe? The annoying blowhard or the sleazy assholes? I'll side with the blowhard in this case. He's a twit, but nothing in his writing makes me think his character is nearly as bad as the sleazy, greedy, and deceitful bullies who are suing him.
