Oi oi, mangaka are hella busy, he's probably been drawing and not paying too close attention to what the fans are up to. At least, until he foolishly jumped on the Twitter bandwagon...
The "Aizen witing Bleach" thing started over in Capslock Bleach (I'd link but...well, it's not 4chan, I can say that much, at least. XD) and it's been going for a while now. It's where this came from:
Or rather, I made that FOR CL_B after someone said "Surprizen" about something (I forget what).
Anyway...
Being a comic artist myself, I can totaly sympathize with Jump and all of the mangaka... but at the same time, DUDE get with the times. Print media is dying out, there's a whole world out there that wants to read your stuff, and the internet is a fast and easy way to get gooRAB to consumers. On top of all THAT the economy sucks, so people who normally WOULD buy the manga are opting not to in favor of the essentials (I do enjoy eating... and having a roof over my head...).
I doubt this will effect much though, people are just gonna be more secretive about stuff and things will continue as usual. The industry's known about scanlations for years, they're only just now getting up in arms over it because sales are low (due to the economy being crappy over all, aging audience and various other factors). I really doubt scanlations put THAT much of a dent - partly because while many people only download, there's an equal amount of people who read em, then buy the tankobons later. Not to mention the rest of the merchandising behemoth attached to most major titles (I still want that Justaway. >.>) pulls in a lot of money. I'd be curious to see ALL of the nurabers attached to a heavily pirated series, as in, everything that series pulls in from all of the tie ins.
