This is the kind of thing I'd expect to see utilized by state-level actors who in many cases may be able to obtain internal technical information and tools from vendors. I wouldn't expect this to become an in-the-wild exploit, but for targeted use by agencies with the resources and motivations to identify specific models, obtain them and test against them this kind of thing should be relatively easy.
As an example, what kind of Android device is best used for insomniac tweets? At one point I thought I saw mentioned that it was a Samsung device a generation or two old, so perhaps a Galaxy S5 suitable for tweeting from the tub? That's a known-vulnerable device, elderly by Android standards of "who gets updates" meaning that Samsung and the carriers don't put any priority on it. Sure you can look at things like LineageOS, but since part of the problem here is in the proprietary firmware blob of the chipset there may still be problems that aftermarket OS upgrades aren't going to touch.
For that matter, is Trump's possible change to an iPhone within the last month[1] related to this, and has it stuck of does he still have a Samsung floating around as seems to be the case?
