Unfortunately this aggressive behaviour is typical among companies selling ham-radio related hardware or software. I got into ham radio in 1980, and after a few years the so called "ham-spirit" evaporated and was replaced by money greedines. I am no more into this, and I do not regret the decision I took. Communities that grew around projects like Arduino or Raspberry PI are more open and technologically-challenging than ham radio today. I wonder why a young student should take his ham radio ticket, and get involved with this stuff, when there are so much interesting things in the SBC wolrd, that furthermore require no license at all!
