Well, I dunno. I've seen it as a lesser evil compared to many others.
In ye olden times I had such a horrible time with my cheapo Samsung when trying to upgrade it from Android 1.5 to 2.1 that I swore it'd be my last Samsung, and it was, for well over a decade. During that time I went through some iPhones and a handful of the most popular alternative Android brands.
Since the thread is about Android I'll focus on that. Every manufacturer was hamstrung by one or more of the following issues:
- Subpar hardware
- Difficult and slow RMA process where your device flies around the globe for repairs
- Software bloat, just like Samsung, but from a country I trust even less (China vs SK)
- Very infrequent updates (if you are lucky enough to get them at all), especially once a newer model is out
Now since this thread is about bootloaders this is probably a hot take, but I spend enough of my time troubleshooting stuff at work, so when I use my phone I want it to "just work" and not have to play some stupid anti integrity protection cat and mouse game to access my bank's app. So the last two are not solved with an open bootloader.
Samsung on the other hand has in recent years given me the "just works" experience on decent hardware, paired with frequent updates. And while their authorized repair shop might not be in my city, it is at least in my country and just a train ride away.
That being said, the nerd in me is disappointed in this move, and the recent EU ruling that forces manufacturers to actually support the stuff they sell for a reasonable time even after it's off the shelves might change things for the better w.r.t. other manufacturers.
