HP. This one is easy. Low hanging fruit. For me, I bought an expensive gaming laptop that arrived defective. I asked for a replacement, they denied and required I send it in for repairs. Waited a month for them to tell me there isn’t a problem. Asked for a refund instead of having it shipped back. They said that’s not how it works, they have to send it back first. So I get it, with the defect still, and call to get a refund. They initially deny a refund due to being outside the refund period and offer a “buy back” credit. I had to spend an hour explaining why that’s not happening and why they’re going to give me a refund or expect to see me in court. Keep in mind, I hadn’t used this laptop more than an hour or two and it’s been shipped around and forth for two months. I did get my refund at least, but the headache was insane and I refuse to even look at HP products.

Adobe: Already said by others. For me, it’s because they charge an insane amount of money for barely-functional software. I used Affinity products instead.

Google: They cancel their services so quickly, it’s more like they’ve blacklisted ME. I refuse to pay for anything they offer in the event it will be discontinued in a year or two. RIP Play Music.

Amazon: Prices increase, service quality decreases, value decreases exponentially. The product I paid for at $79/year was far more superior to whatever Prime costs today. Mostly third party cheap trash. Unfortunately, and most likely by design, there are just a few specific reasons I’m forced to give Amazon money every so often. But at the very least, I’m making the highest conscious effort to avoid them.

I’ll update this if I come up with more.

Edit 1: Netflix: They keep removing quality content and increasing prices. Anti-consumer shit. They are both the reason I stopped pirating and considered starting again.
