You know, an RSS feed can be quite elaborate. You can put advertisement in there. You can put links to your merchandise in there. All kinds of things. And then, everyone who syndicates the RSS through whichever app they use, will now see all the advertising. It would actually INCREASE ad traffic. Now, instead, all those little widgets out there that depend on the Dilbert RSS are useless.
Be greatful you are still getting the strip for free.
A person has to generate revenue. If the revenue does not come from those who use the product (in this case the strip) it has to come from either advertisement or selling of user information. Since neither you are paying, nor the strip is getting any information to sell, it has to come from advertising.
A boycott, because you do not get an RSS feed is childish. So stop the I didn't get RSS Wahh Wahh, crying and grow up.
