My first thought on these matters is usually "unscrupulous affiliate."

This is particularly so when the writer hasn't bothered to contact GoToMeeting first. The fast reward loop behind posting sensational and confrontational headlines unfortunately tends to outweigh the backlash from not doing basic research before publishing.

For that matter, it's possible that MeetingBurner took out the ads in attempt to generate press. There's no way to rationally conclude who the bad actor is, if there is one, because the writer didn't bother to do their research before holding their hand out for traffic.
