> Spotify is thriving on Apple platforms even though Apple has had its own music products for longer than Spotify has been around.

Some portion of Spotify's success, I'd argue, is that they were the first successful entrant in the streaming space. The product isn't particularly remarkable compared to other options and in fact has some notable downsides (such as its ever-changing-for-unclear-reasons UI) but it's what people know and thus what people use.

It having a free ad-supported plan is also a massive factor, but I suppose that would fall under "lowering the bar".
