I'd say they are more indifferent than clueless. I've read that adobe makes about 5-10% of its revenue from flash. They can build html5 tools (see edge.adobe.com) and still retain their core business, and hence profits. I wouldn't be surprised if they have been removing resources from flash for years now.
Look at what it took for them to get to embrace HTML tools, all of which are very recent. Whiney full page ads, screeching blog posts, deleted 'fuck apple' tweet tantrums. I agree that they're getting into some interesting stuff, but the path they took to get there was less than dignified. If they're indifferent now, they started out maybe not as clueless, but petulant beyond belief.

Recent? I don't use Adobe tools one way or another, but recent is hardly the word I'd choose. It's been, what, over a decade now, or near enough to make no matter[1]. Yes, this starts with Macromedia, but it isn't like Adobe isn't working with a group to build useful tools. Just because they support their own format doesn't mean they aren't supporting other formats.
This doesn't mean they only focused on standards compliance. They are a tools company, and they build tools for people to use.
Adobe makes money from selling the Flash authoring tool, but development of the Flash plugin is an expensive cost center. Macromedia and Adobe have spent a decade trying to monetize Flash's huge user population without much success. They can't charge users, but they had some limited success selling licenses/servers for Flash DRM video streaming. HTML5 video is unlikely to support DRM to content publishers' satisfaction any time soon.
