IANANC but my understanding is that a true market is two-sided: it requires informed consumers. Initiatives that bolster the buyer-side of the market aren't anti-market.
Regulations that improve market efficiency are good. Regulations that impede efficiency are bad. In practice, we do need regulations because real-world actors are not optimal rational agents.
The most basic is the enforcement of contracts, which I think everyone agrees on.
But regulations about truth in advertising fit in there too. Lists of ingredients and nutritional information on packaging are an onerous regulation that allow consumers to make better informed choices (and so lead IMO to a "better" market). (I think brand ownership transparency is close philosophically to requiring ingredients on food products.) There are many examples of regulations that promote market efficiency, which sellers don't like because they may have been making profits from the inefficiency, or from information asymmetry.
There are of course regulations which degrade market efficiency too, either by regulatory capture or ill-thought out "consumer protection" like price controls, rent control, etc.
My overall point is that the assumption that a market with the fewest controls is de-facto the "best" market should be examined closely - manipulations of the market (whether by regulation, taxes, etc.) should be evaluated on a case-by-case basis based on whether they promote or degrade market efficiency.
Devil's advocate...
Brands can be a mnemonic that helps customers quickly recall relative quality experienced in previous purchases. This may vary across brands, and my experiences with Dove soap don't tell me anything about my experiences with Ben and Jerry's ice cream.
Brands are often silly and misleading and I try to avoid them, but they aren't inherently malicious by default.
Any medium that can manipulate can also inform.
In this case, the information is technically available but obscured such that consumers cannot make educated purchasing decisions without expending an irrational amount of time... thereby reducing supply-side competition.
