I suppose it doesn't help anyone's self esteem to feel they've been voted off or out, especially when they haven't. The IACGMOOH vote is for the people you want to keep and she just got less positive votes.
It might seem like a moot point, but I don't think it's as hurtful as being top of a poll where people actively voted to get rid of someone, even if the end result is the same.
As for remarking on Tulisa's appearance, I haven't read a lot of comments, but personally I was shocked at the things she's had done, not to alleviate any health problems, but style choices that I really don't think she needs, or that serve her well and which looked glaring by contrast with the other women and also the rugged environment. Sadly those procedures have probably come from insecurity and all the negative feedback is only going to make that worse. The DS piece quotes her as saying the channel has been kind and patient, so I hope she's ok, has support in place and takes the time she needs, if indeed that's what it's all about.
