ChillingEffects has a long (but very informative) FAQ on the DMCA that dispels a lot of common misunderstandings.
Some bits that are of note in my opinion is the overview of the takedown process: http://www.chillingeffects.org/dmca512/faq.cgi#QID130
And the fact that the provider /must/ respond to the takedown notice: http://www.chillingeffects.org/dmca512/faq.cgi#QID129
And some information on the counter-notice procedure: http://www.chillingeffects.org/dmca512/faq.cgi#QID922
That's BS.
The hosting provider has every right to support their customer and keep the notice up. We've gone to court rather than do a takedown and prevailed on court costs, and we've persuaded upstream (colo and backbone) providers served by the same takedown notices to leave customers alone (e.g., not blackhole an IP) as well.
Btw, the number one most effective takedown avoidance tactic is to be an absolute stickler for the letter of the takedown requirements. We can usually get 5 or 10 business days of back and forth on our customers' behalf before the takedown mills manage to generate a fully compliant notice.
And if this notice really was just about a review mentioning a product by name, we would have ignored it or at the very least asked the sender to explain under penalty of perjury why the content was not protected under fair use.

Also, the note in question is clearly defective, since it does not properly identify copyrighted material to be removed. The fact that Softlayer threatened to turn off the service due to a defective notice means that it cannot be used as a reliable ISP. Use FusionStorm, they actually read and comprehend DMCA notices, and in cases like this do not even contact their customers.
I don't think that's actually true in this case. The actual language of the law says that for a notification to be effective under the law, it must include identification of a the copyrighted work infringed. Since this notification does not identify copyrighted work (and explicitly refers to trademark), it technically isn't even a DMCA takedown notification, as defined under the law.
Maybe they decided to use the trademarks on the names in the article? Sounds like a catch22 if you ask me. Put the trademark on the word and they serve you up a DCMA. Don't put it on and then you rise the ire of GoPro since you didn't use the mark on the trademarked names of their products.
Eh, what a hassle.
As an aside: this is what happens when Congress "innovates" with the legal system. I'm sure someone thought it was a good idea to make take-down notices not be legal documents signed by a lawyer. But now any shmuck can send one without the threat of repercussions. When you have a device that invokes the color of state authority, you should have to jump through certain hurdles. Having to find a lawyer willing to risk sanctions putting a signed document in front of a judge is a powerful filter.
