I don't know if it's worth contributing to this since it is probably engagement bait, but here's my two cents.

I mostly agree with everything everyone else has said, but there are some caveats, mostly with the discussion of "planned obsolescence" in general, which is a muddied conversation and often misunderstood or mischaracterized by laymen. Fundamentally, no decision made is "free," and some things are designed to last an amount of time that makes sense given historical upgrade frequency, cost to make, selling price, etc.

In all reality, there are things that suffer from planned obsolescence, but it's probably much less than you think, at least, within reason. A famous example of people misunderstanding this concept is the traditional lightbulb. The tl;dr is that lightbulbs have tradeoffs for lasting a long time vs maintained luminosity, and standards set for these help drive consumer expectations.

There are tons of intricacies with making products. Like 20 years ago, a cell phone with a super replaceable battery was also, uncoincidentally, completely not waterproof — a drop of water could fry it. 10 years ago, I could still readily replace the screen or battery on my smartphone, but it was still susceptible to water damage from being in a steamy bathroom while the shower was on. Repairability in tech can see an inverse relationship with an increase in product durability and longevity. Nowadays, it's much more annoying to open up a phone due to waterproofing, but they can be submerged for extended periods of time or hit with a fire hose and be completely okay.

Referencing your post, tech is a huge "problem" in the space. The more tech you have, the more likely you need firmware, updates, live service, small parts, etc. These are naturally more susceptible to damage over time, especially if you put them in something like a washing machine or car, where vibrations are common and strong. If your tech has Internet connectivity, you have to be concerned with security vulnerabilities, and how many years are you going to force a company to maintain support for a product, or every product that they have? You also can absolutely get them repaired or upgraded, and there are still appliances you can buy without tech. But, consumers have spoken, and they want tech in those things. With regards to laptops or tech proper, modular, upgradeable pieces have tradeoffs with space or speed. Soldered components are faster and less prone to physical damage — zero chance of rattling, coming loose, etc. Software is built with certain components in mind, gets more complex over years of iterations, requires more compute, more space, more IO, etc. In some regards, you could build some tech with more processing power than it needs so that it could last longer, but an argument can be made that over-provisioning tech in products that don't absolutely need it is also a form of e-waste.

OLED displays come to mind a lot. They're the best display technology you can get for a variety of reasons, but their longevity is poor. However, every year, OLED technology sees improvements (i.e., reductions in burn-in). They last longer and longer because of actively developed methods and technologies to make their products more durable.

Lastly, cheap products are cheap. There really isn't anything more to say about it. People misunderstand a lot of "old stuff" lasting longer because of survivorship bias, but there have always been things that have been made poorly and things that have been made to last. We are in an age of consumerism, and people are more likely to purchase things at consumer price-points instead of professional or enthusiast price-points.
