This is more stupid, and I absolutely agree with the article it shouldn’t be legal to end support of an OS this quickly, mind you this is not update to a new OS, like is common on phones, but mostly security updates for the OS you purchased with the device.
I absolutely think 10 years should be a minimum, but for PC, I can easily see an argument for 15 years, as many systems are purpose built, and should keep working even if an OS is discontinued.
A similar argument can be made for phones, but maybe that should just be 10 or maybe even just 5 years, which very few phones have. My vote is on 10 years, because what some companies have been doing for a long time, only supporting security updates for 3 years is not acceptable IMO. If the phone is free to install custom ROM unhindered, I would be more understanding, but phones are generally locked, potentially rendering them worthless if updates are not available.
It’s not a burden for the OS maker, except when the OS is the product, and in that case it’s only fair.
With Android the phone maker adapt the OS to their phones and flavor of Android, if they can’t handle maintaining it, they can use vanilla. Google is the OS maker, and I think they can handle the burden.
