If you want serious video then get the Canon C700.
This is a still camera with some video features for boring home movies that all but you find painfully boring.
Those truly interested in video productions have no interest in these hybrid cameras.
This is a still camera with video capabilities.
I get so bored with the drivel from those who complain about still camera video. Same with ibis as optical is far superior and way more so with WA lenses.
Like you, I really don't care for ILC video - just not my thing, and not likely the best tool for the job. I'd be perfectly happy if my camera didn't even have video (not that I'm advocating for that product).
With that said though, I think there is a notable (and growing) subset of users who do want video in that form factor because it is (relatively) compact, and can generate high-quality and shallow depth of field video, and can double as a stills camera. Youtube vloggers seem to really like the ILC form factor for those reasons, and expect to hand hold the camera facing themselves with the ability to change lenses for creative footage. Obviously that is currently a small subset of the market, but recently I read an article which suggested that in some places "Youtube vlogger" is now one of
the most desired career paths for children. If that's going to be a growing market segment in the future, it would be foolish to ignore it.
Further, some of today's bigger vloggers have literally millions of people watching their videos, which are often being shot on ILCs really designed for stills. Casey Neistat has over 10 million subscribers, and while it isn't what I'd call a photography vlog, he does review gear and spreads his opinion to millions of people. There are plenty of vloggers just like him. If Vloggers are judging cameras based on suitability for vlogging and then spreading that opinion to millions of people (many of whom hoping to follow in these vloggers' footsteps), that can have an impact on consumer buying choices in time.
Again, I'm not a video person so it makes no difference to me, but ignoring the video crowd could (in the long term) have negative implications when the reviewers with millions of followers are video people. Traditional video cameras just don't fit the need or the financial capability of many users. I suspect the demands for video capability in ILCs will only get louder, despite the fact that other purposefully designed tools are available.
