MySpace's core business was crappy irrelevant display ads laid out over a crappy CMS, with what we would today call a very small MAU base. MySpace at its peak was around a third of the size Twitter is today in terms of MAUs. Facebook has algorithmic targeting of ads second to none on the planet (most of which happens entirely outside the purview of ad blockers) and pretty unrivaled view of what customers are doing across devices. On top of which they have several other businesses that could one day grow more profitable than FB itself. We can talk about whether Facebook's model is sustainable, whether demand for behavioral targeting ads will hold up, or if the likes of Instagram and Oculus can ever turn really profitable - but a MySpace style collapse is more or less out of the question.
