This news comes as neither surprise nor disappointment to me.
As I see it, all operating systems have "release" in common. Some (like Debian) roll, others like Ubuntu "drop". All have a starting and finish line. In the end the Debs (squeeze, lenny, etch, sarge, woody, potato, slink, hamm) are on the os scrap heap with the Ubuntu, Linuxmint and other "non-rolling" releases. To me it is like the difference between a marathon and a sprint. Better yet, it is like the difference between the vehicle owner taking care of regular maintenance on the weekends (for fun or profit) and leaving major repairs to a mechanic. In the end, the vehicle owner will pay for maintenance and repair one way or the other. Some folks do neither maintenance nor repair and simply trade vehicles ("distro hop") periodically. I prefer open source (Linux) to closed source because I like doing what I can of my own maintenance. My "computing" experience improved when I shifted my attention from closed source (referring to Windows 3.1) to Linux (open source). (I can tear the engine down on my 1967 Ford truck, but lift the hood only to check the fluids and belts on my 2008 GMC Envoy. For everything else, the Envoy goes to the mechanic.)
I realize that I am more a philosopher than a technician. (I can have philosophy without technology, but can not have technology without philosophy. I have been informed of a change in philosophy regarding the technology.) Mine is an acknowledged philosophy of technology, or technological philosophy. So I may be better prepared for change and obsolence than those who put their stock in their technology to the neglect of their philosophy. Whether an individual's philosophy will pass or not is debated. The obsolence of the individual's technology is indisputable and inescapable. Whomever, if anyone, thought that SolydXK was the immortal os was simply not thinking clearly.
The July update of the home edition did not break my system. However, it caused some minor irritations which I suspected had potentially major implications, and for which I could not readily find solution. It became more worrisome than I wanted to deal with at the moment. I test drove the business edition in a virtual machine, and then installed it (alongside SolydX, SolydK, Linuxmint DE, Linuxmint 17 XFCE, Ubuntu, Xubuntu, and Windows 7 Pro - oh, and Debian Wheezy which I boot into with less frequency than the others; the machine I use the most is a 1TB GPT drive with 300GB of unallocated space). SolydX was my "working" os. SolydX BE may be my new working os. I will see how it goes. The point is that I was for all practical purposes moving away from the home edition anyway - at least temporarily.
Perhaps a deliberate and thorough education as to the practical differences between the home and business editions will go some distance to allaying the angst of users who favor the home edition? Assure them that this is at worst a tempest in a teapot. Sell the advantages of the BE and help them make the transition. (I know that I am saying nothing new to anyone here, just emphasizing and encouraging what are to me potentially beneficial thoughts. I certainly mean no harm.)
In the end, I am more concerned with the well-being of Arjen, Amadeu, Jocelyn, Scott, Frank, Sam - "the team" and "community" than with "the product" whose obsolence is ultimately indisputable and inescapable (a question of "when", not "if"). Take care of yourselves and one another first and foremost. If there is a future in anything it is in the individuals under the "hood" of SolydXK. If everyone took my philosophy, Arjen et al could close the doors on SolydXK incorporated at no cost to himself or others. Even if I am wrong, it's worth mentioning and thinking about.
If it helps anyone upon whom the burden of this change rests to hear it, rest assured that my modest investment of capital and time in the SolydXK product has not been wasted, regardless of its future. Best wishes to all!
