It was a generalised statement of the trend these days. Posters (on forums and Facebook), regardless of age, seem to have become quite lazy over the years.
SAU is a good example of this. Lots of new threads with easily answerable questions if searched beforehand. The time it took for them to sign up (no problems with that) and create a new thread, they could have Googled/Binged/Duckduckgoed the answer(s).
BTW I didn't read the 'heated exchanges', I just thought "fight fight fight" .
