If solitaire is the only example we can use of M$ switching the tables we better find some other examples.
OK I've found a better example.
Visual Studio 2015, the tool that develops Sonar and other M$ applications is now subscription only. Or you can rent it. So they are turning into the Adobe subscription model. Same with MS Office I guess...
I'm screwed as I have a standalone Visual Studio 2013 Pro license which seems to get me nowhere....
It wasn't that long ago you would get a free copy if you attended the right release shows.
The OS I'm sure will remain "free", probably even after a year I suspect, they want people to buy/rent their other applications, as everything else. Nobody will buy windows standalone any more anyway as it will come included with new OEM machines in future.
