No, my comment is about how camera manufacturers seem to mess up power management. The issue being directly addressed is not being able to power your camera directly from USB-C (two replies above the one you quoted). This is only a minor inconvenience that, in and of itself, nobody would say that it in particular is why they use their phone instead of an ILC, but one has to admit being able to use and charge their phone at the same time is really convenient. People use their phone over an ILC because phones are so convenient, and minor inconveniences like this add up to casual users. This also affect serious users - for instance if you want a long time lapse. Powering the camera from USB-C is not out of the realm of possibility and I can think of several uses that I alone would take advantage of. @Gibba suggested that it is intentional so as to sell more batteries, which may be true, but even more batteries doesn't address long timelapses or a studio setting.The high cost of replaceable batteries is a factor in people using devices with disposable batteries instead?
$90 for a new battery is nothing compared to $500 for a new iPhone when it's battery goes.
Boggles the mind…
Apple will replace your battery for 50-70 USD and I'm sure there are cheaper services out there. I'd say that's hardly disposable, and cheaper than an OEM camera battery by your pricing, especially when you consider somebody will have take your phone apart to replace the battery. People may use the aging battery as an excuse to get rid of their phone, but that's consumerism at work. You and I both know that there are camera users out there that will get a new body because their easily replaceable batteries are getting old under the same premise of "it would be nice to upgrade". It may be less prevalent, but it definitely happens.
