Indeed, I remember the first year the Virtual ticket came out, Our money situation wasn't great, subbing to wow was basically our entertainment for a month, no extras (take out, movies, buying games,going to concerts of out for dinner etc) it was tight. But I knew months in advance that Blizzcon was happening so I just popped a couple of pounds in a jar every week till I had the £25 to pay for it.
It was a treat for us, being in that situation money wise. But it's down to each person to reason whether it is worth it for them or not. No need to be angry at people that don't think it's worth it, just as theres no reason to be angry at people that do think its worth it.
