sounds more like Mario is afraid that he'll get beaten on the track by some independent team using the same equipment as his team, only doing the job better than him. It has happened before...

This is the reason why you haven't heard any bad press on this from Ferrari, Mercedes, Honda... The main teams will have the newer & better equipment, while the independent teams will get the more basic packages and will build their own teams from that, including the hiring of their own personel.

Thiessen's idea works only if there was sufficient reason for other manufacturers to consider supplying or creating an F1 team, and at present that's just not the case. The cost is just too prohibitive for those outside of the present company to create a working budget, and the way Ford left the game two years ago gives them nothing but incentive to look elsewhere for a motorsport programme.
