Don't mean to minimize your complaint but this not the first time you've complained about Adobe. Over the course of a few years and many updates I've had few if any problems with Adobe software and when I did customer service responded promptly. That's not to say I haven't had problems caused by my operating system or hardware. Fortunately it's such a popular software that a little Google research will usually give you the answers you need to get going. Out of curiosity I went to chat today, and as I suspected the overwhelming majority of problems were either hardware or operating system issues. Very few if any tech support or help desks will help you diagnose a problem with OS or hardware, unless there is a known conflict.
I can't speak for all but having spent a ton of money over the years on business software, I can say the level of customer service I've had experience with is in direct proportion to the purchase date unless you buy a separate help plan or are willing to pay $$$ on an individual use for answers. I for one prefer the subscription plan, as every year between business, financial , other software, and the updates to same I'm going to spend a certain amount whether it's by the month or in a lump sum, for me it's a cost of owning a computer. Having been burned on purchases many times over the years, I much prefer to not have several thousand dollars invested only to find out something doesn't work, and the company's gone.
The nice thing about the subscription plan is you don't have to renew, no one forces you to continue for perpetuity. If you're truly not happy with it buy a stand alone. For those that don't want to pay rent there are any number of options out there at all price levels. Just remember you don't own the software you buy, you own a license to use that current version for a certain period of time or until the company decides to stop supporting it. Then you basically own a coffee coaster (assuming you got a disk and not a digital download).
