Why would I not? Is Canonicals involvement a new unit of measure I somehow︀ missed? Because last time I checked Ubuntu Touch is supported by UBports foundation and it︁ has over 8000 community members working on it, so what you just said makes absolutely︂ no sense to me, why are you spreading misinformation?
And it is not years behind︃ in updated, OTA-4 was released this January and OTA-3, 3 or 4 months before that,︄ so once again I ask you, why are you spreading misinformation?
Now to SailfishOS, what︅ does "isnt open source it just relies on open source components" mean?
Why would I︆ not rely on a sole Finnish company for updates? You seem to be fine with︇ relying on Ledger, a single company. I rely on Jolla because Jolla makes money selling︈ it's products, so that tells me a bit more about where and how the development︉ is going, not only that, but even if Jolla was to stop supporting it, I︊ can easily move somewhere else.
It's been years and I'm still waiting for that attack︋ surface to be attacked, meanwhile both Ledger and Trezor have had multiple leaks and people︌ are still losing crypto to this day, because their emails and phone numbers are everywhere︍ in the interwebz. And thank you for the suggestion but I'll stick to my smartphone.︎
Ubuntu Touch has an installer, you can find more information here:
UBports Installer • Ubuntu Touch • Linux Phone
Worth mentioning, at one point in the past I hired my very own developers and I've ran my own apps (crypto) since then, not sure if I've mentioned that before here in the forum, a lot of these smartphone versions might not have a wide selection of crypto apps so the best solution is to make your own.
