kohlrak: Anymore, it's just a real pain in the bottom to find everything that needs to be turned off, and that's ignoring OEM software. PCs getting locked down in the same way as smartphones and tablets is a legit fear: it was a major concern with UEFI's introduction. That should be enough to spook everyone: the choice between x86 and ARM is the only thing that separates OS lockdown rules, and ARM's planning on competing with x86, and intel doesn't necessarily have a problem with that, since they too can make ARMs, it then becomes less competition and more "upgrade," which will be mandatory for new hardware that just won't support x86 when intel stops support.
StingingVelvet: It's absolutely a legit fear, I just don't think we're anywhere near panic mode yet. There's a long, long way to go between Windows 10 and a version of Windows that won't let you run a fan mod or whatever. Also I don't think it's anywhere near in Microsoft's best interest to push for that, since their core business base needs to run unique software and whatnot. Also I don't think they're ignorant of gaming's influence over their success anymore, like they were before Steam and WoW and other such public successes.
In other words there's a lot of reasons for them to keep things relatively the same, streamlining the experience for those who want it while keeping it open for those who don't. The shortsighted and likely self-defeating greed required to override all that is certainly possible, but I don't agree with those who always act like it's inevitable.
You'd think, but the no-ip fiasco paints a completely different picture, and as a victim of Microsoft's irresponsible maneuver I can tell you it really did happen. "Locking down the OS" is a hugely successful method of getting rid of viruses, for the most part, which is the biggest thing to plague microsoft (since everyone and their brother of a company is trying to cut down on tech support requests, including microsoft). Moreover, locked down OS means no alternatives, in the long run. It wouldn't count as a trust violation, because microsoft windows simply becomes the default and preferred product, even without their direct influence on the situation (so they can't be held liable for it).
The kicker is: most customers have internet, don't believe in wire-gapping, and those who do will just be treated like those of us who play old games: "That's archaic" "That's deprecated" "everyone makes payments on their computer hardware, which includes the OS anyway, then they upgrade as soon as it's paid off so what's the difference?" and other such arguments.
But you're right: it's not quite fear mongering level, yet. Instead, people who see it coming should be preparing for it. Coincidentally, right now, there's a growing market for open hardware and hobby processors and such. Ultimately, if enough is enough, the right people can be put into a position of making a "slower but more free equivalent." Tablets, phones, and computers that are open and aren't obligated to follow UEFI standards, but they might just not have the same power (at first). This also would allow for alot more competition in the market, which is better for everyone. I'm kinda hoping microsoft does this, and intel ends up doing what i predict: the end result will be as dethroning of silicon valley elites as Trump's election was to the US political elite (regardless of what you think of Trump himself and his politics, he totally dethroned politicians on both sides of the isle by being a nobody, and this is the real reason people voted for him, because america loves knocking people down a peg).
