Historically, yes. Labels generally had very little to do with concerts.
These days, a lot of artists are signing "360 deals", which means that the label receives a cut of basically all the artist's revenue streams, including touring and merchandise.
My impression is that it's generally considered to be the only option in most cases. In certain segments of the music industry, major labels are still basically the gatekeepers. Wanna be the next Modest Mouse? Fine. You can put a few records out on a small indie label and do pretty well. Wanna be the next Taylor Swift? You pretty much need a huge label like Universal. The discovery channels for certain types of music are a lot narrower. If you're an aspiring pop singer, you need pop radio. And you won't get it without major label backing.
So the labels have the power to basically say "Here's the deal we're willing to offer. You can take it or leave it". Most artists would probably be better off keeping the majority of their touring profits (since, along with licensing, I think that usually tends to be the biggest source of income) -- but if they're stuck between a bad deal and no deal, a lot of artists will take what they can get.
Adele's mega success is absolute proof that this is not true. Her label, XL, is a true independent and ushered her to multiplatinum status.
The big labels might have taken a hit, but general consumption patterns have hit smaller artists, venues and labels as bad if not worse, if only because their size of revenue was smaller to begin with.
To be clear, I don't think that's necessarily a bad thing. At this point I think the record companies can be viewed as quite a bit more parasitic than they could have been in the past. Not because they've changed, but because the ecosystem has changed to provide much of what they offer in alternative, cheaper ways.
Disingenuous is the implicit assumption in their argument that music and the music industry is all about them.
I think in a link that consists of a few paragraphs and a big graph showing revenue over time, if the revenue for every segment except one is going up, but that one segment goes down enough to cause the aggregate to go down, that deserves mention.
To me, the topic is loaded enough and the case obvious enough that the omission looks purposeful. I applaud the goal of the article, but I can't do the same for the method.
