Playing devil's advocate here - we know voice information is being sent back to both Google and Apple, if the analysis were done server side dissembling apps isn't going to show us anything we don't already know.
While I do suspect they listen, I have pretty solid (anecdotal) evidence they scan text messages. When I bought my house I had no solicitor, I text my buddy to see who he used and he texted me a response.
Started to type into Google to get a number and it was the top suggested search after 2 chars. Nowhere else did I mention this solicitor, hadn't heard of them before this, have no other searches for this solicitor. It's not a big firm, it's not even in my city - only explanation I have is they scanned the messages.
Sounds more like a tooling issue. The tech exists, the hardware can run it but the tools don't exist to make it feasible in a reasonable timeframe/with a reasonably sized dev team. Corners are being cut on optimization or relying on hardware brute forcing it.
Thats a bit tame, first page of the British passport is:
"His Britannic Majesty's Secretary of State requests and requires in the name of His Majesty all those whom it may concern to allow the bearer to pass freely without let or hindrance and to afford the bearer such assistance and protection as may be necessary"
Oi you, this is my mate and you're going to look after him, alright.
The utterly bizarre thing to me is I don't really think he's tried to hide any of this. Like he's pretty much doing what he said he was going to do, he's done it before, why did anyone think he was going to do anything different?
I'd also imagine Google won't be prevented from owning a browser indefinitely - if it's still worth it they'll create a new browser and try to recapture the market, further diversifying the market.
I try not to be too Linux fanboish these days, but what in the ever loving fuck is that about? Windows sounds like it's reverted to 90s/early 2000s novelty crap and browser toolbars.
It's a genetic superiority I'll have you know, +30 resistance to anaesthetic.
