It seems to me that many companies offering workshops / legal seminars etc. are trying to use FUD (fear, uncertainty, doubt) to convince private aircraft to buy their (management, in this case) services
Absolutely.
In this context: EASA will soon offer a template OM-A for non complex NCC operators. For free. If you attend the AERO in EDNY and the seminar by AOPA, then this might be of interest:

Several German soon-to-be-NCCs have teamed up with AOPA and IDRF (Interessengemeinschaft der regionalen Flugplätze - the german association of regional airports), EASA, the swedish CAA and the German LBA and have crafted a template OM-A, which is right now circulating within EASA for final comments. This OMA will be EASA compliant and thus a national CAA will hardly be able to reject it. It is high time that we (NCCs) participate way more in these matters, as the lobbyists do "plough their fields". EBAA are of now help, as they are - IMHO - hopelessly on the side of management companies and don´t want small ops to survive.
