It still doesn't matter. GE is run by its own management and engineers. It doesn't matter that its all owned by one Chinese conglomerate or NBC or whoever. They're not re-badging Shenzhen #1 Super Fast Machine with the GE tag. Corporate ownership is, generally, an abstract that shouldn't matter in most cases. Unless they're purposely cutting lines or just rebadging stuff, then reading reviews is still the solution here.
I also noticed he didn't mention any giant German brands like Bosch or Miele. Nor any Japanese brands. Or less popular brands like Amana or Admiral or Hotpoint. Again, this space is full of competition. Compare that to tech where we have natural monopolies all the time or a duopoly, at best, with lots of little third-level competitors that barely get sales.
Car guys fall for this fallacy too. Latte-sipping Fiat engineers with only small car diesel experience who are appalled by off-roading aren't designing the new Wrangler. The Wrangler is its own design and designed by the same engineering team that worked on it before the buyout. The 2018 Wrangler won't be a Fiat mini with slightly larger wheels. It'll still be Wrangler and reading reviews on it will be all that matters. Of course, this can change, but the idea that a single large owner depresses the market and hurts quality is questionable. They do, of course, have a big advantage with pricing and other market advantages.
