I just like collecting old and obscure HW and actually use it. WP8.1 is unusable: Store shut down, no new apps. Logging in with your live account doesn't work anymore. If you were already logged in, you could keep using it for quite some while, but in January, the calendar stopped syncing with your live account, and since then, it will regularly wipe all appointments you add, so it's completely unusable, even without cloud sync. MSN weather is also broken, and I can't get an alternative app.
Today you can show people how tech from 30 years ago worked. The same isn't true for anything made today, or 10 years ago.
I wonder if we need similar laws for electronic hardware?
I'm not saying you're wrong to want some support, or at least the ability to unlock - quite the opposite - but I find your reasoning a little faulty.
We lost that chance when we didn't treat smartphones like computers when it started performing functions of a computer, Then Appstore/Playstore happend and now they are literally the first computer for majority of world population but rather than bringing regulations to treat phones like computers, Manufacturers are now allowed to make computers like phones.
Microsoft didn't bother to fix it. (look at the WPInternals project, through which this is possible)
For the Surface RT, they didn't push firmware updates to fix the bugs allowing to unlock it either.
I hate regulation, but what else can you do if voting with your wallet doesn't work, as majority of people don't understand the issue or don't care and companies have no incentive to behave responsibly.
They have a great PR machine about carbon neutrality and all that, who is going to notice some old phone destined to a landfill.
It's not even boycotting, just going with time
You're leaving the field for good, have no competing product in your own roster and you can't even provide a bootloader unlock? How is this reasonable? Where aren't anyone boycotting MS for this anti-ecofriendly move?
Windows phones had a nice hardware and would be useful still at least in some capacity if the software stack could be fiddled with. Now they are just trash.
