I came up with two reasons:
1. They're insecure and want to bring you down to make you feel better.
2. They're jealous of your confidence.
Most people that I've come across who think someone else is whatever or something along those lines don't really try to make them feel bad, they're just dismissive of them or look at them temporarily, then go back to carrying on whatever conversation they were having.

Motivation maybe? A lot of people have called me a bully on this site but some people are so deluded in their ways that someone with no filter needs to tell them how it is. If everyone in their life is just nice and jolly about everything and not willing to spit the truth then people in the wrong will never assess their situation correctly. People that overweight need to be told that they are fat. Guys in their 30s complaining about their virginity and trying to spread their misogynist mindset to the rest of the world need to be told that they are losers and need to make a change. Bitter sexually repressed women who try to demonize men for the most petty of scenarios need to be called out as the crazy cat lady. The guy who looks extremely awkward taking a bathroom selfie asking a question on this site as to why he can't get laid needs to be told he looks like an awkward serial killer so he can change that. I think everyone is all too sensitive these days.. have you ever heard of the term "guys just being guys" I'll make fun of any my bros that is a virgin or is fat. They would probabaly insult me back and we'd laugh together. It's not that big of a deal. I'm not very politically correct as you can see lol.0

OK so my mother is one of these people. It isn't about being insecure she just really hates life and finds you in almost nothing.
She will help you if you are in her 'in group' otherwise she tries to see you fail, sets you up and laughs. She only helps to control.
I made really good money at my old job but left to start a business of my own and didn't tell me Mom because she is negative always. Once the business had been off the ground and doing well I then told her I 'was laid off' and 'struggling'. She got so happy and told everyone to the point where people were like calling me telling me to set it right. But she was partying like it was 1999 telling people I failed at life.0
