The anime Battle Programmer Shirase actually thanks fansubbers in its last episode.
Without fansubbing, neither Funimation, nor Crunchyroll, nor ADV/Section13 or Bandai America or any of the foreign anime distributors (eg MadMan or Monolith) would exist. Fansubbers are responsible for the industry outside of Japan and for many of the purchases of anime DVD/bluray/LD/VHS/CD, toys, games, dollfies, cups, figures, models, books, postcards, posters, etc from Japan.
The Japanese government commissioned a study looking at piracy of anime products and found that, piracy actually boosts sales and rentals of DVDs:

Workers starve less, the more shows are watched. This is counter the kool aid that Hollywood spreads.
Fansubbing is one giant marketing tool. Now this only works if the users purchase the shows they find worthwhile or purchase merchandise - such as CDs, games, figures, plushies, tea cups, etc. Of course this is an issue for each individual. However, if you support the industry in a honest way, I think you are helping the people who make it more than if you shunned the work altogether. It’s really your call. If you’re only leeching and spending the money on other stuff, you’re being dishonest.
In a global world, regional licensing should not exist. One should be able to use a service like Crunchyroll to download episodes and watch them for a reasonable fee or for viewing of ads. Further profit can be generated by sales of merchandise. Those fans who really like their hobby, end up buying some merchandise related item sooner or later, instead of spending that money on domestic entertainment.
We already have a globalised economy. Copyrights and availability of foreign TV should reflect that.
For Americans, one can “legally” watch all recent release anime (live) with two subscriptions, one to Funimation and one to Crunchyroll. For about $13/month you can watch everything and support the starving Japanese animators, who will continue to starve because wages are low anyway and profits still go to the select few, who rip off common aspects of pop culture, public domain and other anime shows. Most anime shows are tolerated rip offs of other shows. So much for copyright.
For foreigners like myself, who pay a full sub to Crunchy, we get a limited repertoire of works despite paying the same price as Americans. FUnimation does not even let non-Americans subscribe. I would gladly pay them using PayPal. Already services like MyUS exist to allow non-US customers the ability of buying from shops which only ship to USA. But one never knows if FUnimation doesn’t label one a criminal if one uses such a service and a real PayPal account with real cash on it.
