It's fans that keep this franchise going and it's fans that spend billions of dollars each year on Star Trek merchandise and tickets to attend Star Trek conventions, not the general public.
The figures I've read indicate that CBS makes about $20 million a year from original series merchandise (presumably, each successive spin-off draws in a little less than the show before it). If the franchise ever made "billions of dollars" from merchandise and convention sales, those days were over long ago. Given the age of the fan base we're talking about, continuing to target them isn't the greatest long-term strategy.
Also, considering the bump in sales that have occurred for "Prime" Trek on home video upon the theatrical and home video releases of both Bad Robot films, I don't think your complaints about the "real fans" versus the (fake?) fans have much merit.
