Can someone explain why ToppDogg is not an appreciated group?

I have just started to watch some of ToppDogg's MV because I randomly found them on YouTube. I haven't really looked into the group yet, but it seems like they have good music and great personalities but they are not popular. Why is that? Is it something to do with the company? Or something to do with the boys? I know that there has been drama with the company and the members are struggling, but I can't find that many articles about it. I thought that asking this community would be best because I can get more information than just reading a few articles. I hope you guys can help me understand since I'm a relatively new kpop fan. https://www.youtube.com/watch?v=tZZ-lPbZNuY ^ If you guys haven't seen their new video its pretty lit. https://www.youtube.com/watch?v=T44qEPYUdGk ^ A video posted by ChoNunMigookSaram where ToppDogg Pronounce Western Female Names
