Thanks for updating the page to say "Hitec," I think it's an important step forward.
2) Providing the dimensions makes the work for copycat manufacturers much easier.
I don't buy that argument at all, for two reasons:
1) I think we can all agree there is no secret IP here. There might be copyright, there might be trade dress, but those are not secret.
2) The trick is in execution, not in design -- running a store, and getting customers to come back.
And, by the way, making sure that paying customers get the information they need to make a purchase decision is an important way to make paying customers come back.

(or, really, any part page from those catalogs)
These are from well-known, large, companies that are known to go out of their way to serve their customers, and thus are doing very well. Copy-catting isn't solved by making it harder for paying customers to find information.
Then again, it's not my company, and you can do what you want, but I can also choose to do more business with companies that are more responsive to requests for information I need.
When it comes to "sticking to servos known to work," that's OK if you're buying a full system. Personally, I had some spare servos of a particular type, and was looking around for various things that could fit them, so in the category "have servo, will buy bracket." Also, Lynxmotion is not the only store that sells these brackets -- the exact same description is found in other places on the web at various resellers (Trossen Robotics, for example.)
