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 don't know anything about any of these groups (I do like anime), but they had to know from the beginning that voluntary subtitling would never make any money. Even if copyright law were intended to help regular people rather than giant corporations, their work was entirely based on material they had questionable "right" to use in the first place. They scratched their own itch, and later CR had an itch too. It could…
Exactly zero of the fansubbing groups ever did it to make money. For most people, they were in it for the community, which included things like the prestige of having your name associated with a popular/successful project. The reason the fansub community was upset at CrunchyRoll was because not only did they take the content, they edited it to remove the intros and other forms of attribution to the original fansubbers.
If they had left in attribution, nobody would have cared, and CrunchyRoll would have been treated like any number of other torrent to streaming sites that existed.
