Absolutely. There is no "right" way to perpetrate telemarketing. The only difference between this creep and the slime that he sued was that this guy is careful to adhere to the technical minutiae of laws that seem to have been partly written by the telemarketing industry themselves. This was just a sordid story of one antisocial jerk using the courts to extract money from a less savvy antisocial jerk.
I especially like his use of "appreciated". I'm sure I appreciate getting a recorded call telling me whom I should vote for.
I disagree, it depends on the telemarketing, though I do agree that the vast majority is terrible, and that anything using an automated dialer is terrible.
Colleagues of mine in sales sometimes telemarket - in that they will cold call potential customers, but only people they have researched and genuinely think might want to advertise with us, and the track record of a.) people called who end up spending money with us and b.) of those people, the ones who are happy and become repeat customers, does show that in this situation telesales works great for both us and them.
On the other side of good telemarketing, I'm in a position to get plenty of cold calls / cold emails myself, business related, and it's not rare for me to get one that genuinely interests me, and sometimes leads to me spending money with them and getting good results from it. So I don't mind getting those calls/emails.
Outside of business I find them horrific, I've never had a good cold-call to my home landline or my mobile, presumably because for non-business sales it isn't worth doing any research into who I am and whether I'm a valid target.
(But yes, I agree with your judgement in this particular instance.)
