I wish my experience were similar, because I'm also the kind of person who doesn't buy cheap tat and does do his research. I only buy from reputable sources. I typically buy mid-range products at minimum, and often towards the higher end. And I have still encountered dramatically more failures generally but also dramatically more deliberate crippling of products in recent years.
I do agree that there is some element of modern technology simply being more complex and/or working on smaller scales and so inherently having less margin for error. Whether I really need a more vulnerable 4TB hard drive instead of a more robust 1TB drive if I only have a few hundred GB of data to store anyway is a different question, of course, but bigger numbers presumably shift more boxes so that's what everyone supplies.
There is probably also an element of dumb luck in my personal anecdotes. I had an amazing lack of failures for many years, with not so much as a hard drive giving out on me during its working lifetime across many different machines. Statistically, I was well into the long tail for that period, and what I've seen more recently may in part just be reverting to the mean.
But that doesn't excuse things like printers that decide your ink/toner has run out after a fixed number of pages when you can see there's plenty of supply left, or tablets that get security patches for barely a year or two before some OS update designed for newer hardware leaves them barely able to run any more, or cars where diagnosing a warning light on the dash means an expensive visit to a dealer but adding a simple report of the underlying fault code to the already pathetically bad onboard UI would mean owners could fix the problem and the clear the error in five minutes themselves without paying. These kinds of trends are rampant in their respective industries, even among big name brands and high-end products, and they are nothing but customer-hostile cash grabs.
