Apple chose an internal connector that worked with their CPUs. They couldn't even offer the connection styles on PCs; they worked differently.
Apple built its own mouse and keyboard cabling because they wanted to allow their users to connect their mouse to their keyboard, and to start the computer from the keyboard. No common cable offered them that.
Apple was literally first to the common rigid diskette. That they came up with file systems of their own is a measure of their early investments, and their need to maintain compatibility. They couldn't move to FAT, they had already made their own stack.
From my side of the fence, PC makers were laggards trying to save pennies who couldn't be bothered to invest in better technologies. Apple's success in cornering the majority of profits in the computer sector is a measure of their continued failures.
There’s trade-offs, but in most cases the Apple call has tended to err on the side of ease of use and ease of access to the mass market at the expense of flexibility and versatility for tinkerers. It’s good for a market to have companies willing to make different sets of trade-offs to please different segments of the market rather than all herding around the preferences of a cluster of nerds.
The real problem is that the rest of the industry has “Apple envy” and just copies everything they think they can get away with instead of making their own sets of trade-offs.
For the majority of apples history their products were incredibly niche mostly used by designers because certain admittedly superior software for these professionals only shipped with MacOS.
The ipod and iphone were the first true mass market products.
And even to this day PCs and Android(outside the US) dominate the market share by user count.
PC and android are not for tinkerers and nerd, they are the default, apple positions itself as the premium.
But that's often the right route. Sometimes what the others are doing is not enough to deliver a good result. Micro-USB sucked, so they made Lightning. Flash ran slow, so they helped kill it.
