Who cares if the TA is gagged? Their job is to accurately and efficiently handle the back end processing for shares - NOT to be a substitute for company spokesmen.
All of the info about authorized and outstanding shares, institutional and insider holdings, float, fully diluted figures etc. should be readily available directly from any public company.
If this info is not available from the company, or or if you you need to cross-check with another source, you have a bigger problem than a gagged TA.
