Not shooting the messenger here, just the message.
This is like the Navy buying a car that worked pretty well when it was new, but now that we've had it for a year and a lot of different people have driven it you can't drive until 30 minutes after you start the engine.
Thousands and thousands of the Navy's cars have the same issue.
We just shrug it off and nobody does anything about it- nobody with stars on their collar solves the problem.
The bloatware/resource hog thing isn't entirely the Navy's fault, that's just the nature of the computer industry, but the Navy deserves a lot of the blame for going along with it.
Again with the car analogy, that 140hp Ford Taurus isn't good enough anymore. You probably use this new car for the same things you always did- email, spreadsheets and powerpoint, but the latest software is optimized for 143,360hp. Much less than that and a year from now you'll hate this car even more. It's not that the new software is any better, it's that the hardware is better so the programmers got lazy, they added a bunch of stuff nobody really needs, and we can't take it out. So "optimized" isn't the most accurate word but the budget people don't like it when we call it "shitty."
