The subtitle "Load an OS on Raspberry Pi without a microSD card" is pretty inaccurate - you've been able to netboot a Pi for years at this point, which is arguable superior to any local storage (SD or USB) when the Pi will always be connected via ethernet.
You do realize that these devs, and the rasPi foundation make ZERO money off of anything they do. I'm sure most, if not all, have regular day jobs, and do these things as a hobby. That being said the boards were originally and still are meant for educational purposes, everything else is just candy. The Pi was never meant to be a PC replacement.
If you're not happy with the pace of development from all the hardworking devs in their spare time, not charging a dime for their work, feel free to get on board and start coding yourself, if not stop complaining and I'll gladly point you to a 200$ Chromebook.
