Why Ashneer had always a problem with startups in shark tank?

I have always Wondered why people started praising Ashneer just because he was roasting the entrepreneur's startups? He has a Odd Lot mentality or a reverse physchology to give negative opinions in each and every startup. A Good Business man is the one who can sell anything , Obviously there are a lot of scope of improvement. Few startups which were humiliated by him are literally doing well without any modifications into their products. Simply, he was pretending to be cool by making reverse statements or roasting those startups. Probably the reason why he was sacked out from his startup 😁 Lol
