“Microsoft will make businesses pay 15% more for licenses that let workers access servers from as many devices as they want, which – depending on how workers do their jobs – may still be cheaper than the alternative.”
If some brute stood on the sidewalk and demanded $5 to pass, would that ever be a good deal? Nope. Not even in an emergency. The brute would just slow you down. If the guy charges $5 to go on the left side while he charges $7 to go on the right side, he’s not offering any savings. Call the police to arrest the guy. If M$ charges you any amount of money to access any number of devices (taxing your own LAN!) it’s never a good deal. Stop using M$’s stuff. The EULA on the client OS licence limits you to 15 devices, for pity’s sake. Don’t accept that. Don’t pay M$ to get around an obstacle M$ created.
Use Debian GNU/Linux. You can download it from here. The price is always the same, $0, and you can connect together as many devices as you want. You can turn your PC into a server or database, too, at no extra charge. In addition you can examine, modify, run and distribute the code.
