I don't see anything in your description that would imply that those who claim Microslop is performing at below-average-quality right now, can NOT be the underlying cause either. For instance, it may be that the problem is difficult to fix AND that Microslop is really really incompetent at solving this. That is one possibility at the least.

I am not sure why that would be an explanation either - it could be that enterprise gets more time and money, whereas the non-paying free-riders naturally get less. This would also make sense from a business point of view (to some extent, though if only enterprise would use github, it would lose its status as main source code hosting website on the planet quickly; others are already waiting to nibble away at GitHub, the more Microslop fails here).
