Ayyy this is interesting to read. The main takeaway is that JB and his gang don't want to be on MD anymore because:
a) MD wants to go legit (1st post)
b) Got mean things said to them, https://mangadex.org/data/91b484cee39632f23da5adeb466966b7/x15.png
Unfortunately, the evidence they presented for (a) is an out of context screenshot of some chat taken last year, and has already been given context by admins on the top of the 1st post of this thread. Please do read it. Basically going legit is a pipe dream and ONLY A DREAM.
For (b) though, I've read some arguments from both sides. 1 is better moderation in the forums especially towards crybabies who demand chapters immediately, I think that's a fine argument. But I've also read that some SL were pissed when they had some series sniped from under them and wants to be THE official unofficial scans, which I can't wrap my head around, we get it, you got pissed because of some other groups is sniping the series you put work and effort into. But let's say that I wanted to read Kaguya and it's delay-locked but there's a convenient link linking to JB in 1 click? Convenient. But hold on, some /a/nons translated it on MD and I don't have to go to another site and just read it right here and now? Obviously I'm reading it here purely for the convenience, not to mention the ads and crypto miners some accuse JB of having (I use adblockers anyway so I don't care if the allegations are true or not, please don't quote me on this).
I feel that after 28 pages, while acknowledging that mods are gay, the arguments hold no water. So comes the arguments arguing that JB and his gang are just after that sweet sweet ad and patreon revenue, which is relatively fine for me, but be aware that these groups operate on a grey area bordering on illegal. If somebody comes and "snipes" the series from under them, they are also operating on the same grey line that JB and his gang operates on, even if after all the hard work from scanning, cleaning, translating and maybe a million other bullshit that scanlators deal with. While illegal, C&D only comes once in a while which makes this a lawless land, people can and will snipe your series, or worse, aggregators will just take what you scanlated and put it up on their own sites without even leaving in your credit page.
Don't get me wrong, I appreciate all the hard work SL groups go through. As a programmer myself, I also appreciate what the MD admins are going through. I do support the delayed chapters implementation because there's a link to the SL's site and don't think it's an issue. I hope this drama can be water under the bridge in the future because I rather have MD's implementation than other shitty manga aggregators that I'll be forced to use.
