This is 100% true.

You might wonder why, if businesses are the target, why not just make Windows a no-frills, solid base for the other offerings? Why slop it up?

The answer there is cultural. Windows needs a large team just to keep supporting it at scale. All those engineers and PMs need career paths, and shiny things with which to sway their managers into promoting them. The strong, experienced, leaders have largely left because they know this isn't a company priority. So you end up with B players promoting C players for slop.

Time goes on and the Bs become Cs, and so on.

So the dynamic is that something that isn't a priority doesn't merely slop evolving, it devolves. We're now several iterations into this process, which will accelerate due to AI.
