Of course it can be debated! That's what the forum is for! Don't let a simple thing like the facts get in the way

But seriously, there's no harm in debating the general principles. For what it's worth, I can see what User3143 is saying, I just don't think it's quite the point here (btw, I don't think he's trolling either, just rather insistent!)
Yes, a cyclist should shoulder check before changing lane. I think that's basic road safety and I doubt anyone would disagree - but I think that misses the point. I think what's in contention here is whether a driver on a roundabout should, having seen a cyclist, take just a little more care... especially when nearing exits. The situation shouldn't have arisen that a cyclist gets knocked over regardless of what they have or haven't done, not where there's good cause to expect the unexpected!
