I totally understand, that because of liability and some more availability of resources, you would expect a company product to be "safe". BUT: if it is your butt that is going to be in the line, then I bet you: you will be much more careful that a random engineer in some random company. About the resources available in a big company, they are usually more directed to marketing, legal (including lobbing to avoid right to repair) and oder areas to maximize revenue, and not exactly in quality.
I worked in 2 different big companies which worked in "mission critical systems" and boy! I can tell you some stories about how unsafe is what they do, and how much money is invested in "cover your ass" instead of making products better/safer.
