They decided not to upgrade most of their mobiles from wp7 to wp8. They promised not to do that again, then did it again when they decided not to upgrade most of their mobiles from wp8.1 to wp10.
Windows 10 is rubbish for reasons I'm not even going to explain because we all are well aware of them. They also have inconvenienced millions of people to make us upgrade even if we didn't want to.
They got rid of all their QA. Quality of all of their software has gone downhill since then. They don't care.
They put ads in their OS which we already had paid for.
They are doing all they can to get rid of win32. That's going to be their bane, as win32 is the only reason most of us still use windows.
That's all I know of the recent Microsoft.
Fuck Microsoft.
