This came up in the Robinhood checking thread a few days ago. "Do you really think that you're going to outsmart a financial institution that employs people like you (but smarter) because you happen to be better at math than your facebook friends who studied polysci?" The hubris of people in tech who think they're the only people who notice things is getting really tiresome.
Having said that, I think that's a slippery slope of a stance to take, because it stifles creativity and novel solutions, which history shows often come up when they're not looked for. But I think that's kind of the sentiment of embarrassment they were expressing: "groan, another techie is going to disrupt something that doesn't need disrupting."
Edit: To the people responding to this (and downvoting): this person asked for an explanation for why someone would feel embarrassment at this. I was trying to give what I thought was a reasonable explanation. I don't actually feel embarrassed by this, I was just trying to understand and articulate someone else's feelings on this. I'm sorry if the explanation didn't do it for you.
