This is the reason why I sometimes don't like John Gruber (even though I am usually a fan of his work) et al.
Tell me again how Adobe's decision of killing perpetual licenses and forcing subscriptions down their users' throats made their development cycle quicker… Tell me that with a straight face. Meanwhile, Serif already delivered two entire apps (Affinity Designer 1.5.4 and Affinity Photo 1.5.1) with full Touch Bar support in the MAS, under a perpetual license. Technology preview? Only in Photoshop? Coming from a major company that must've had early access to the Touch Bar API portion of Apple's SDK, otherwise it wouldn't have been featured in a keynote? You have got to be kidding me…
