Looking at the sibling I currently see right below hits the nail on the head as in vendor lock in is bad for both SaaS and perpetual licensing models. I think none of the models currently work well for the consumer. If your SaaS provider shuts down its service you have to replace all the hardware too because of vendor lock in. If your perpetual license vendor stops making this produ t line or changes its proprietary software incompatible say 3 years down the line (which from a software development standpoint is reasonable actually) you can't buy another light switch for the new room you added by subdividing the basement "play room" that would work with your original installation. Software incompatible. New software or other vendors' software won't work on your 'ancient' hardware. Vendor lock in bad.
