It's amazing how uniformed MS is about Apple products, and how uninformed so many people are about WHY MS ads are false and different than the "mac v. pc" ads.
Ease of use, "better" claims, things like that are subjective. But price is OBJECTIVE. MS, when they created their ads, was not lying about price. But they continued to run the ads after Apple lowered their prices and upgraded their products, and by doing so, MS was acting in bad faith. They were falsely advertising, an actionable civil crime in every state in the USA. They can be fined. By refusing Apple's request to pull or alter the specific ads that make false claims, MS may have dug themselves a hole.
The main ad in question is the filmmaker who claims that there is "only one model under $2000, and it has 2GB of RAM." That is a FALSE claim, and MS continued to run that ad for weeks after knowing it was false, including during the NBA finals. That's blatant.
As for prices being cut "$100 or something" that's just an MS tool not knowing his competition. Prices were cut by far more, and features were added, including the oh so important 4GB of RAM.
That makes MS's advertising objectively false, not subjectively false. That's the difference, and that MS ignored this request means they are very likely liable for their actions. Each and every time this ad ran after being notified of the claim, they could be fined by every state it ran in, as well as be required to pay Apple damages.
That the MS tool is bragging about breaking the law is hilarious. He should be proud...
