I think it depends on what is considered an acceptable list of features that the camera should have at the point of release. As consumers, we often have no say. Take the example of my mobile service provider, which charges fees for a myriad of services, including caller id display, caller id non-display etc. Some of these services used to be free, until they start charging, some are still free but they may start charging in the near future. Then, there are ‘bundle deals’ such that most of these add-ons come ‘free’ but one then ends up paying more. On the whole, it becomes rather confusing, all in the marketing name of providing ‘more choices and flexibility for the consumer’, i.e. it ‘enhances your freedom to choose only what you need’, ‘it gives you full control over how you want to manage your life’ etc. Regardless of the slogans, these amount to achieving even greater profit for the service providers. Does the company have a ‘right’ to making profits? Sure, they do, but these should stay within ‘reasonable’ limits. As to what constitutes ‘reasonable’, it is another can of worms. Nevertheless, an example serves to illustrate the extremes that companies go towards profit-making if they can get away with it. Remember EpiPen? Mylan, which then has a monopoly over the product, had increased the price of EpiPen from US$100 in 2007 to over US$600 in 2016, despite the cost of an EpiPen dose of epinephrine remaining at around US$1.
With Canon going down the road of paid features updates, I am afraid that list of startup features will dwindle to what they can get away with, and that the price of the camera would still rise, probably slowly at first before getting back up to pre-paid features days (taking inflation into account, that is).
The flipped side of paid features updates is that some people do not need the complete start up feature list. Should these people then ask Canon to remove the unwanted features and sell the camera at the cheaper price? I somehow do not think that will happen. It will likely go the way of how the mobile service providers have evolved. There are now bespoke plans, just like building a PC from scratch where you buy ‘only’ what you need. Unfortunately for most (or perhaps only some) people, these still end up being a lot more expensive. I used to pay about $30 a month for my previous 2-year contract plan. The essentially same plan, with lots of marketing materials saying how wonderful it is, now costs close to $60 a month. I am not saying this happens to all people, but it certainly happened to me.
The outlook is not great for the consumer (over-generalising here, but when has it really been good on the whole?), so I’d better enjoy what I get now.
