Flash forward to a some years from now, when the simulpub craze has died down, the apps shut down/licenses expired, and once popular manga are entirely unavailable to read after certain cutoff points, except on a collection of sketchy aggregators, or by hunting down massively overpriced physical releases.
I get dropping manga when they get licensed, I really do. But this simulpub shit is going the same way as streaming. Too many cooks in the kitchen, all doing their own shitty systems, with licensing across platforms being an impenetrable jungle of unavailability or expiring access. MD is great because it's a central archive (that won't give your computer aids) for stuff that never got licensed in your region/at all outside of Japan, and you can just read it whenever. Simulpub with its limited availability, both time- and region-wise, and whacko monetarization models is ruining this good thing we've had going for a long time.
