The differemce here is that there are other ways to build that digital crutch with less complexity and engineering. I don't think anyone is saying image sabilisation isn't great, but IBIS as a specific technology is unnecessary and complex, and like it or not adds cost. GoPro have neither lens nor sensor stabilisation and yet somehow don't suffer at all from movement in a tiny lightweight body. The main issue here is people with "decades of experience" not accepting change and insisting that they know best. With technology sometimes no experience at all is better.At one time, these were all called "crutches" by some people who learned without them and felt they were unnecessary if you knew what you were doing.
