"Everyone needs (or will soon need) a replacement toner cartridge. Each manufacturer uses different specifications for their cartridges so that there can't be a high quality universal generic cartridge, and so people are stuck buying toner from the firm that sold them the printer. This means the printer manufacturers can charge what they want for the toner. All we have to do to gain the market is the following: (1) mimic the form of the cartridges, (2) fill them with toner, (3) price them at about 80% the cost of the official cartridges, and (4) make sure we sell them as 'compatible' and 'not authorized by the manufacturer'. That way, when they don't work well people will simply curse themselves for buying the knock-off. As toner purchases are generally infrequent, we only have to get each customer once in order to make a good deal of money."
While Eero did not stick to his scheme long enough to become filthy rich, others with more skill at creating knock-off products picked up the baton and kept his idea alive. While we cannot establish any ties from "compatible toner" to organizations bent on the destruction of society we can unequivocally state that they are, if not Evil, at the very least evil.
