Ubiquity. They're just a software zombie shambling on at this point.
the software is basically unupdated for quite some time outside of their new cloud only inferior products, and i've tried reporting bugs to the support multiple times and every time they just are clueless, drop the issue entirely, or find some trivial way to argue its not actually their fault when it clearly is, like an on demand bgp crash under specific common private as peernig config as one example.
They had a wonderful product for the price point in multiple areas, and basically all their replacements have been inferior and often flaky.
Do you have any anecdote on human talent exodus causing a failure, or are you riffing on the company in general?
