A shill?
From Wikipedia:
"A shill is an associate of a person selling goods or services, who pretends no association to the seller and assumes the air of an enthusiastic customer. The intention of the shill is, using crowd psychology, to encourage other potential customers, unaware of the set-up, to purchase said goods or services. Shills are often employed by confidence artists."
I have nothing to do with Apple except I own some of their products. If they have been sending me checks, I sure haven't been getting them.
If your disatisfied with a company, get rid of of their products. Don't simply come here and tell everyone the stuff is crap.
As far as the anger/sarcasm, whatever...
