Probably not. And speculating simply about revenue might not really be an issue. What worries me, is the road that starts us down, seems like it could be a slippery slope. If we're willing to speculate about that, why stop there? Why not speculate about profitability? Why not speculate about the salaries of company employees? Why not speculate about whether or not the car someone is driving is appropriate to their means? Where do you draw the line?
In my opinion, you draw it early, and don't speculate about information that is really none of your concer

In the persuasive/argumentative sections of college classes such as speech and writing classes, we learn that the slippery slope argument is invalid, and for good reason.
"The slippery slope fallacy takes its name from the image of a boulder rolling uncontrollably down a steep hill. Once the boudler gets started, it can't be stopped until it reaches the bottom.
A speaker (or writer) who commts the slippery slope fallacy assumes that taking a first step will lead to a second step and so on down the slop to disaster.
If a speaker claims that taking a first step will lead to a second series of disastrous later steps, he or she needs to provide evidence or reasoning to support the claim. To assume that the later steps will occur without proving that they will is to commit the slippery slope fallacy."
(from The Art of Public Speaking, from the chapter Methods of Persuasion)
How do you reason that simple speculating about website revenues from premium members would result in speculating about the salaries of company employees and such?
Saying something will lead to something else is a fallacy unless you provide reasoning that such a something will lead to something else. "Why wouldn't it lead to something else?" is not reasonable.
