Big difference between playing a few chords because those are the only ones you know, and playing a few chords because you consciously select them.
Either way, like hip-hop today, this leads every 15-year old in the country to believe that being a musician is something that takes effort. It's possible for bands today to form, buy instruments, learn to play them, and have a hit in less than a year. Which is just so wrong, on so many levels.
Judging from the rest of your post, did you mean "little effort"? If you did I agree completely, current music is in a sad state.
Another band that writes very simple 3 chord changes is AC/DC, the majority of their songs are incredibly easy to play on the guitar but that doesn't stop them from writing great music and sticking around for almost 30 years. Simple does not always equal bad.
