You can never please SJWs, no matter how much you bend backwards. They'll always find something to complain about. That's the meaning of their entire existence. That's what you're missing.

Not exactly. Messenger has been End-of-Lifed except on Windows 2000 (in all territories) and in China (on all platforms). On any other platform or territory, your login is refused and you're told to upgrade to Skype.
As rpgmaker states: You can still use the network, though.
There was a recent discussion on the FreeBSD ports mailing list about removing some msn related ports (i.e. users complaining about removing ports, exactly because of the reasons stated by rpgmaker: It still works)
It is technically possible to block the IP ranges of reading/caching web apps, as well as refusing to show content to readers blocking ads, but few providers bother. Neither usage scenario is practiced widely enough to significantly impact ad income, except on sites that serve a very tech-proficient userbase.
You can do the same thing for free with various browser extensions, of course, but then again, you can filter ads with browser extensions, too, and that's the only or major benefit that a lot of sites offer you as a reward for subscribing.
One should think of this less as a sale of services and more as willing patronage of the arts.
It serves a technical purpose just as much as their ego. It makes it possible to search for someone with a specific make and/or model of product in order to ask for help or recommendations, or gauge someone's expertise/seniority/subfocus within the forum's focus during a discussion.
It's actually really simple. The display works in a way that you control the polarization of outgoing light (but the intensity is constant). Then you filter whichever polarization you want. So a black dot on a white screen could be achieved with a small vertical polarization region on a horizontal pol. background, and filter out the vertical pol., with a polarizer horizontally aligned. Align it vertically, and you swap the intensities.
Note: In this case the light whose polarization is controlled is the reflected incoming ambient light, which isn't polarized; in a computer monitor it's the back light.
I very much doubt that any business except the smallest mom-and-pop store could run entirely on Chromebooks. Certainly no IT business could run on them.
