You speak much truth, but I think ther is more open source than even Microsoft sees in the ecosystem. Getting started producing working projects feels easier in .net to me.

I was a Java developer in the early days, and found the platform very frustrating. Things started to improve with the spring framework. And when I heard about spring boot, I was very pleased to see that it was all about making a standardized easy initial project startup configuration.

I recently had to do some Java for the first time and literally decades. I was able to use Java 17.

I felt it was vastly better than the early days, I was frustrated by things like the incomplete implementation of generics. And it appears that was a direct result of the way Java evolved.

Unfortunately, it appears many if not most Java projects are still stuck in Java 8 because of all of the Legacy installed code and a lack of decisiveness toward upgrading.

As for .net, I'm a little worried about some of the things coming out of Microsoft lately. I fear they may be returning to some of their old ways. Time will tell.
