To a degree. When Steve Jobs came back to Apple for the second time and the company was going under, he actually made it a point in keynote presentation that the collaboration with Adobe (especially as far as Photoshop was concerned) should be intensified. A few years later, the CEO of Adobe appeared on a Stevenote and he was extremely enthusiastic about Apple.

I'm not sure what happened then, but one factor might have been Apple developing their own software to replace Photoshop, Aftereffects and other creative tools. That couldn't have been good for their relationship.

From the user perspective, dumping Flash is still a good idea. If only web video didn't rely on it, everyone could just uninstall it or at least they'd all run a Flash blocker plugin that was enabled by default in browsers. So I guess the hate triangle between Apple, Adobe and their users built up to the point where Adobe staff just go "whatever" when there's a technical problem on the Mac.

Adobe's best bet is now the Windows world, where there are much less viable alternatives to its creative suite and where there are less geeks around who like to install Flash blockers. It also makes sense from a business perspective as the Windows platform seems to be much more enamored with keeping legacy apps functioning. Compared to that, stuff for OS X just stops working when the next big version arrives.
