And that's just it—the expectation from the general public has been reduced to almost zero. It used to be fansubs thrived due to taking 2+ years (if ever) for series to come out officially. Now you have people whining if there is even a one week delay in the English, as many series receive a simultaneous digital release alongside the Japanese broadcast.
Viz has a number of manga that are simultaneously published in English and Japanese on the street date of the magazine. Yet there is still a large nascent market of scanlations that release days ahead. Excuses I've seen from people amount to "if they have the content finished and sit on it, then its their fault" despite the fact we're talking only a handful of days so that a coordinated release can be made. (Takes a few days for print copies to make it to all corners of the country)
Although to be honest, I believe most of the stuff being released ahead of street date is because of a certain group of individuals called Mangastream that has turned it into a bootlegging business. They do it for the ad revenue on the website, which the Alexa-rank is higher than websites for the actual publishers. Then you have counter-groups that attempt to beat them to release to cost them ad hits. I'm honestly surprised the industry hasn't gone after Mangastream despite them poaching pretty much the entire Top20 best-selling manga series in Japan and receiving millions of hits monthly.
