It was only 2.5 years between Apple's first device with Lightning (iPhone 5 in September 2012) and their first device with USB-C (12" Macbook in April 2015). It's not like Lightning had a huge track record at that point they just made a decision that they had switched connectors once and didn't want to turn around and do it again. Kind of understandable, but I'm glad to not have Lightning anymore.

Failure to have clear cable capability marking from the start is too bad though, if I needed a high speed USB cable longer than 6" (probably included with a hard drive enclosure or similar) I'm not sure if I own one, and if I do I have no idea which cable it is.
