Seems far more likely that you've been incredibly unlucky. I've had many Macs and have never had battery expansion or logic board failures. I know many people that still use their 2013-era machines and they're still chugging along.
My wife has been using Macs for a long time now while I use both Macs and Dells with Linux and, occasionally, a Lenovo or an HP. We have gone through at least 10 Macs in total and none of them failed in less than 8 years. One got a puffy battery (replaced in warranty), one got chipped when it fell from the desk (a white MacBook, Apple replaced the bottom, keyboard, and palm rest for free, even though the machine was out of warranty, but was listed in a recall for the palm rest). Some HDs died and some flash got upgraded. While it's not a daily driver, even the white MacBook is still going strong (as is the Bondi Blue iMac, the eMac, and the dual G5, none of which get much uptime these days, but boot up just fine every month or so). Both our current Macs (a 13" Pro and an i5 Mini) are from 2014 and will be replaced by M2 ones because they can't get the newest OS (while I can get away with it, my wife won't for long due to professional compliance rules).
No consumer-grade PC laptop or desktop of mine lasted that long in active use (some x86 servers did, as all the Sun and IBM PPC/POWER stuff) without extensive overhauling. Even my Thinkpads got cracks after five years.
The thing that worries me the most with the newer Macs is the flash storage - when it dies, I don't expect them to be repairable. I hope Apple includes M.2 slots in the future, even if the laptops need to be bulkier because of that.
