Just forget all this Advertising Standards stuff.
It has absolutely nothing to do with the ASA, ...in any shape or form.
This was nothing more than a piece of journalistic misinformed nonsense on a light news day, fed by PTC's
PR department and,... it worked for them!
There is nothing whatsoever which comes under the remit of the ASA, so don't bother with the letters.
If you feel compelled to write to someone write to the broadcaster, but I can't imagine that they are going to admit to appalling research!
That said, I agree, this is a shocking piece of dangerous journalism.
