A big part of Apple's marketing strategy is to create an entire experience around their brand. If you don't have Apple products, you're on the "outside". This plays perfectly into that strategy.

That's partly my point, but also the notoriously bad quality of the stream can't be doing much to boost the confidence of existing customers. Additionally, being in the middle of a workday, many current Apple users and fans may not have access to an Apple device right now.

It just seems like a lose/lose situation all around, but they stubbornly persist.

There's a Safari for Windows though isn't there?
