Are they going to ship an official cross platform UI library any time the next century? Decades after the Java lawsuit they still ship only a crippled copy of their scrapped Microsoft JVM for other platforms.

Aren't almost all of their contributions for integration with their proprietary technology?

Yes, they got worse. They maintained Windows XP for ages and you could actually feel the improvements they shipped. Windows 11 meanwhile makes me wait for them to add a robotic arm with a knife as hardware requirement, to improve the backstabbing experience.
