The biggest issue I have...
...is with developers and hardware manufacturers who hide their forums under HTTPS lock and key to current customers only. When researching a new product for my company I need to know the good and the bad up front so I can make an informed decision on that purchase. Spending 20,000+ pounds on a solution to find out it has issues with your brand of firewall after the check clears is not a good thing.
Manufacturers who communicate with customers and potential clients equally get my support and more important, my business.
