Not to me, it isn't.
There are plenty of areas-of-interest that attract both hobbyists and serious academics alike - which also tends to attract unwanted attention from callous legal departments who are keep to adopt a shoot-first-ask-questions-later policy - things like (lawful) research into DRM techniques, retro video-games (and not ROM hosting), infosec disclosures, and so on - so if you're really into those areas and want a safe place for your lawful content but without worrying about your site/content/services being taken-down without good cause then it makes sense to side with a provider who is able to resist DMCA requests.
