Trying to draw a parallel with Ezra's Mashim makes an awful defense.
Judging from their ridiculously aggressive attacks on EN, and the lengths they went to stop them, this fellow's reasoning makes total sense.
Of course in addition to the argument that there are supposedly many Hatzalah's around the world (using that name) which have no affiliation with HQ.
This is awfully similar to unofficial Chabad Houses, and the lawsuits which they faced for using the name Chabad or Lubavitch by Corporate Chabad et al.
In either case, leaves a bad taste for people to donate to them (referring specifically to the Corp HQ), when they see how their resources are being used.
