I’d rather it not be acquired, but if it were, I’d much rather that it be acquired by Apple. That company doesn’t currently have a full-fledged image editor in its software lineup and probably wouldn’t cancel or cripple the product. As Adobe already ships several full-fledged image editing tools, I don’t have much faith they would leave this product intact.
I use Adobe products for much of my day, but I still hate them for what they did to GoLive CyberStudio.
Those 2 have an obsessive, abusive relationship. Adobe cancels Premiere for the Mac, Apple releases Final Cut Pro. I wouldn't be surprised if Apple has a mole in Pixelmator who calls the Apple batphone if Adobe starts to sniff around their office.
I do agree with you that Apple and Adobe have a strained relationship, it has been so for decades. However, your example isn’t correct.
Apple bought Final Cut Pro from Macromedia in 1998 and released its first version in 1999. At the time, Adobe had been releasing new versions of Premiere for both Mac and PC for years, and the product only went Windows-only in 2003 (when it renamed the product Premiere Pro.) In 2007, it started releasing Premiere for both platforms again.
