My own undergraduate degree program was well known among students as a relatively easy major for people who wanted good grades and didn't want to work too hard. There was an honors track for the people who wanted to work harder. I'm not sure if that was the intention, but that's certainly how it worked out.
I'd say that one degree program being less difficult than another doesn't make it fake or unserious though. It's just natural that some topics are harder than others. There's a qualitative difference between "unserious" and "easier" I would say.
