I think we should include Apple in that.
Apple chose ADC when VGA was the 'standard' Where is ADC?
Apple chose Firewire…but where was/is the use of Firewire on PCs? It's there, true, but it's hardly used as a standard in the PC community.
Same with Lightning. And we could argue the same with the old 30-pin connectors. Only Apple uses these ports so there's no 'standard' amongst manufacturers.
If USB hadn't become as popular as it did, maybe Apple would have been using a different port. Old, classic iPods are FW for example. Apple couldn't stop USB, but it seems to like dragging it's heels on USB-C.
What about Thunderbolt? Do PC manufacturers use that? How do you have 'standards' if only one part of the industry uses those ports?
Well this isn't very compelling...
ADC should be compared to DVI. The standard VGA popular at the time was objectively worse, literally comparing VGA's analog to ADC's digital video....
The first G3 macs that shipped with Firewire also included USB. So you could use the 400 Mbps firewire or you could use the 12 Mbps USB. Options! While it expanded some of the iPods functionality its intended purpose was for professionals generally in the video editing space. The hundreds of FireWire PCI cards (PC only btw) still available today should illustrate how it was extensively used by PC users at the time.
Firewire, 30pin and Lightning cables were required for features not supported by USB until much more recently with USB-C. Things such video/audio out, car dock mode, and Apple charging protocol (Apple 12watt USB 9watt) plus it was conveniently reversible. There was a 5-6 year gap between Apple releasing the iPhone 5 with Lightning connector and competitors smartphone using USB-C.....
Apple couldn't stop USB? Oh boy....this may surprise you....
Intel invented USB and it flopped until Apple picked it up with a colorful design for the translucent iMac where it gained traction market wide....
More recently Apple was one of the largest contributors to the USB-C design and specifications. Then they single handedly made the port popular across the entire market. Strategy was simple, revive a dead product SKU "MacBook" (not Air or Pro just MacBook) and not only make it the first computer to use USB-C on the market but only give it USB-C. This way anyone that bought it couldn't avoid it like half the use used ports on most laptops. In short order aftermarket got on board with accessories, cables and adapters. Finally PC manufacturers started to include it. Apple using a dead SKU allowed them the freedom to fail as it wouldn't effect their more popular MacBook Air and MacBook Pro product lines.
Tech blogger John Gruber was told by an insider that "Apple invented USB-C". Now I find that a little far fetched but its implementation is perfect for a Mac while sharing a lot of similarities to Lightning plus Apple had a lot of engineers on it. Regardless to say Apple couldn't stop USB doesn't make sense since they were instrumental to it....
Oddly there was a Nokia tablet with USB-C that beat Apples laptop to market with a rushed design that failed. And while USB-C has more potential than Lightning however not much an iPhone would benefit from. And without a compelling reason I find it unlikely Apple will use USB-C on an iPhone....admittedly a compelling reason could be government regulations.
What about Thunderbolt? Apple set the bar for that with the USB-C/Thunderbolt in the 2015 MacBook. Therefore all PC manufacturers use Thunderbolt 3/4 in their mid to high tier laptops and workstations today. Dell Precision, Dell XPS, HP Enterprise, Razor laptops, Lenovo ThinkPads, Microsoft Surface, etc etc all use Thunderbolt. Only low tier laptops designed for a basic experience at a low price don't have a thunderbolt option...
