Yeah, disturbing. If it continues, more and more programs will have cloud only subscriptions that completely control your access and credit card.
Like Dub said, try Libre Office. 5 years ago, Libre and the sister Open Office project were a good intended attempt to give a free, open source alternative to MS Office. Was a joke then, but not now. Still has the quirks being worked out, but up and running on my rigs and getting closer to slaying the giant. My old copy of MS Office was cut throated by MS themselves when win 7 was not backwards compatible with their own word processor. The bastards had notifications that they were weeping with compassion with us in every step of the ordeal. Be of great joy however because they fixed the incompatibility problem. Just bring out the credit card and for the right price, all would be bliss.
F*** them. Installed Libre Office and missing nothing, although just a lay user. There is the lack of a replacement for MS Outlook. Seems the most popular replacement for Outlook is Mozilla Thunderbird and installing their calendar ap when using Libre or Open Office.
http://www.libreoffice.org/ Parallel situation with graphics. Adobe Photoshop is about king of the realm. Open source and free competitor is Gimp, likewise a substandard program 5 years ago but not now. Most of what you could do in Photoshop can be done in Gimp. Excellent program that anyone dealing with graphics should be aware of.
