Yeah, there are a lot of bottom bracket standards, most of them aren't proprietary, they're just different. Bottom brackets are a lot better than they were 40 years ago too -- back then you could pull them apart, replace the balls, repack the grease, and change the cups and spindle. And you had to. Now, you get a cartridge BB or a minimal pair of cups and some standard bearings. My sealed bearings now last a lot better than my cup and cone ones did.
Hubs are similar. Cup and cone bearings can be maintained, but they pit, and no one ever really had replacable races. So if your bearings were bad, you replaced the wheel. With better hubs, you just pop out the bearings and pop new ones in.
Old school (7-8sp) Shimano jockey wheels _never_ spun freely. Sram 11 speed ones, even on apex, spin beautifully, and in the case of my gravel bike, are outlasting the derailleur.
I think we're in kind of a new golden age of cycling. There are tons of interesting bikes being made by small providers, using 3d printing, old school steel fabrication, custom carbon. There are tons of small company parts -- most CNC, but some additive. Basic non BSO components are pretty reliable, and even Shimano's low end isn't that bad for the casual crowd. There's a niche for everything, tracklocross or basket bikes or cargo or gravel or mountain touring or full squish. And there are even road bikes too.
iFixit has some good rants, but this isn't one of them.
