Not entirely their call. I have little sympathy for the likes of Sony, Samsung et al but they’re also beholden to the entertainment industry which is very VERY pro-DRM (and the like). Open Source standards will make it much harder to lock down TVs and make it easier to pirate shit (or, you know, actually fully own your TV and do whatever the fuck you want with it). They won’t be dropping those ‘calls’ any time soon, not unless pissing off the entertainment industry worked out as more profit.
Obsidian can be almost anything you want it to be. Try searching out some videos from folks who use Obsidian for journalling.
