Halo effect? Shamalo effect
I can almost NOT see a company of reasonable size, that is all virtuous that i would be happy to do business with. In almost all cases, you're doing a deal with the devil.
Oracle: Predatory licensing practices, but I do use Virtual Box on my mac.
Apple: Walled garden (good and bad), union-busing behaviour in Apple stores, and certainly anti-competitive, but I own plenty of their devices
Microsoft: Convicted monopolist, tendency to release crappy software, but managing their products is how I get my beer tokens at the end of the week
Broadcom: Blatant disregard for customers through astronomical price rises
Amazon: Complete disregards for workers rights, or mental health but I do love my kindle (I avoid using the Amazon store and side load my books)
Google : I just avoid for their privacy invasive techniques, ditto Facebook. The above list are almost as bad at protecting privacy as well/almost as good at monetising privacy.
And that's just off the top of my head. Not restricted to tech, as well.
Just because I use a product does not mean that I will automatically like the company that produces it.
