I don't think Sony will ever pull one like this on their fans.
If it makes any sort of financial sense, you better believe that Sony would turn PlayStation into a service. In fact they are already in the process of doing so, to a point. Look at their streaming service as one example, or how about how they are handling backwards compatibility. same as Nintendo, who are also preparing to branch out to other platforms, such as Android and IOS. You even have the likes of "playstation TV", which allows you to hook up a PS4 game pad and use the PS now service. As well is PS now also been usable on certain blu-ray players and TV's. So yeh, Sony very much are heading to the "service" route.
If you are thinking along the lines of anti-consumerism, then Sony have also been known to do far worse things that are considered anti-consumer than Microsoft have, but people always forget about that stuff and rag on Microsoft instead.
We have the rootkit scandal of 2006 with Sony music CD's, which was a massive one. Which not only allowed Sony backdoor access to your PC, but also 3rd party hackers. Then there is the fact they waited almost an entire month before telling people their credit card information was potentially stolen in the PSN hack.
As for if this will hurt the sales of the Xbox one, I highly doubt it. A lot of people just do not want the hassle with using a gaming PC, as
@SlipZtrEm pointed out. Some people just want to buy one device, and not have to worry about system specs or anything else. And there is a major misconception about how much a decent gaming PC costs. Anything setup that costs between £500 and £800 will last a fairly long time before any upgrade need doing it it. Hell, for the £500 I spent on my system, I have a GTX780 in it. Which will last me a good while before I need to replace it. And I do not just game on my PC, I also do videos for youtube. I do digital art in photoshop, I dabble here an there with 3d work. PC's just allow you to do more, plus you have a lot of compatibility with gaming peripherals, such as racing wheels, fight sticks, joysticks, and game pads.
Personally I have always been a PC gamer over a console gamer, and the only reason I buy the xbox still, is for Forza. If Forza comes to PC, that will actually be a good thing. The PC racing community have been begging for a game like Forza and GT for years to just chill out with, and there is not one single game like it available. The biggest draw to PC gaming for myself, is the fact I can get the latest games that interest me much cheaper than I can on the Xbox or PS4. I got Fallout 4 for £25 on the day of release, same with GTA5. I got F1 2015 for around the same, and Farcry 4. The list goes on. This is why you barely ever see my playing any other games on my Xbox, baring Rockband 4, and occasionally black ops 3 (which I only play with my other half, as I own it on PC also), or the older rockbands or guitar hero games on my 360, which I still find fun to play. I very much prefer buy multiplats on the PC over the console. The savings on buying games on the PC are immense. Then you have the likes of humble bundle, and you can get a great many games exceptionally cheap. And at the same time can help out a few good causes.
So far I have gotten a "firaxis" developer bundle on there, borderlands bundle, an EA origin bundle 2 (was also gifted the Origin Bundle 1 by a friend), star wars bundle, humble jumbo bundle 3, and a Warner bros bundle. All have multiple games each, possibly talking about 50 to 60 games in total from humble bundles alone, and all for around £56.
Then there are steam sales, origin sales, and even Uplay sales. And online stores such as greenmangaming, who are very reputable and have some amazing offers all year around. Currently I can pre-order Farcry Primal on there for £26.
(the X1 sold more, though, so you do have a point)
