I "upgraded" Adobe Reader DC. I highly, highly, highly recommend NOT doing this. This morning, I uninstalled this program and rolled back to an earlier program. "DC" stands for "direct cloud" or something like that, and every trick is used to get you to use Adobe's "cloud". When you open a file, 30% of the screen on the right-hand side is dedicated to the "cloud". You CANNOT prevent this side-screen from opening, except on a per-file basis. (You can use control-h to get it to close, but who wants to do that?) Also, when you go to save a PDF, the initial save screen is to Adobe's cloud. You have to hunt and go through multiple screens to save the file on your computer. I highly recommend staying away from Reader DC.
Why would they do this? The only thing I can think of is that they're no longer a viable company and need another money stream. Hence, the "cloud". (My Asus computer had something similar -- store info on the Asus cloud! I uninstalled that right away.) My prediction: Adobe will not be a viable company 10 years from now. Flash is getting replaced and soon PDFs will too.
Other companies that might not be viable 10 years from now, in my opinion? Microsoft. Windows 8 was horrible. So horrible I had to upgrade to Windows 10. Another point: Microsoft buys Nokia because no one is buying windows phones. They had to buy a manufacturer of phones. Then, they basically take a write off for Nokia. Why? Microsoft thinks they need only software and the "cloud". But someone needs to make windows phones, and the windows phone ecosystem is barren of apps (ask me, I have a great phone -- Nokia 1020 -- and even like the operating system, but there are no apps). Another case in point, if you use Windows 10, when you go to shut off your computer, there's a "metro" like interface that pops up. The idea is that you'd use apps in that interface that run on your phone, table, computer. But I've never used that interface and no one I know who has Windows 10 has used that interface. And I can't think of an app I want to run on my phone and computer. So, Microsoft thinks they're going to become an app seller, but I can't see how Windows 10 helps them. To me, I don't think we'll see Microsoft around in 10 years, at least not in its current form.
Another company that might not be around in 10 years: IBM. They keep selling off their hardware businesses and are trying to be an "online", cloud, and services company. But they're abysmally behind in the cloud, and without hardware, what do they have? It's unclear.
