I certainly don't think it's "deliberate" in the sense that they would ever want to exclude Apps users, but I think it's deliberate in the sense that they saw fixing the Apps problem as a much lower priority, perhaps because they know there's a high degree of vendor lock-in for us (it's not like I'm going to move to a Microsoft offering). From their point of view it could be a totally rational business decision, given finite resources, but it's still shafting your most loyal customers.
