Its been a while since those times. I remember Dattebayo fansubs, one of those torrent fansub groups you're talking about. I remember when they shutdown and announced support for Crunchyroll, suggesting that legitimate paid streaming was the future for anyone who actually wanted to support the anime subtitle community. Perhaps I wasn't remembering the full politics of mid 00s subtitle culture... its been a very long…
I think your retrospective is very Dattebayo centric and distorted. Most big fansubbing groups hated CR back in the days when CR started, since CR took their fansunbs to fuel their business. Once CR started to make/pay for their own translations (also hiring translators from some groups in the background) the situation got better, since then a clear, legal path was visible for the community.
I mean, Dattebayo definitely criticized CR at first. But by the time Dattebayo closed shop, they were highly supportive of CR. That's why its important to remember the names of these groups. Do you remember the large-fansub group and/or which anime you're talking about?
Its hard for me to think of a bigger group than Dattebayo back then. Dattebayo covered Naruto and Bleach subs, as well as a bunch of lesser known anime.
