Does Pinterest own the word “pin”?

Throw in some confusion of trademarks with "you can't copyright a font" for good measure and you have the perfect regularly scheduled "I'm being screwed by a big company that I won't bother to mention is being totally reasonable" post.
We ask you to ... [c]learly indicate that your service is not an official Pinterest service - after all you deserve the credit :)
For a corporate communication of any sort, let alone a lawyergram, that's positively pleasant.
This is a relatively minor incident in the grand scheme of things, but Pinterest is just shooting themselves in the foot here.
While there are some complicated legal issues involved with so-called "defending your IP so you don't lose it", the biggest thing I see here as a developer is that one of the bigger social networks is using its time and energy to crush somebody that is effectively advertising their brand for free and is quite literally no threat to their interests.
As a developer, I see what companies like Twitter do when they get popular and make it difficult for others to build products and this makes me concerned. When Pinterest inevitably releases their own API, why should developers invest time and energy developing products that benefit the Pinterest brand when there's a chance that the effort will be wasted because their lawyers are trigger happy?
Pinterest is one of a handful of companies that has a chance to sort of challenge Facebook down the road. My advice is that their management should work with their lawyers to avoid screwing their own reputation. This is salvageable for Pinterest and an opportunity for them to clarify that they are developer friendly and not a dumb, faceless corporation like Twitter has become.
This is known as the "throw 'em under the bus" technique and is often an infringer's first line of defense.
Note: I'm not taking sides. Just pointing out the phenomenon.
BTW, http://pinteresf.org now redirects to pinterest.com. I wonder if they got a similar letter, and as a result handed over their domain?
Though these can probably be used in court proceedings as "defendant previously received notice/requests from us... which were not complied with" or something along those lines
That said, INAL (I'm not a lawyer), but I believe legally they could argue that because you are using a word that is Prefixed with "pin" and that your product also a service related to Pinterest that there could be confusion as to whether PinPigeon is a product of Pinterest's or not.
I thought the same as soon as I visited the site as well.
