Much more disgraceful than The Met's new logo is that the museum lies to the public. If you've ever gone, you'll know that The Met goes to every length to not only obscure that it's free to visit, but actively tries to get you to pay a "recommended" admission fee.
In a passive-aggressive move designed only to end a lawsuit for its fraudulence, The Met will now call it a "suggested" fee to enter on its signage. Whether its employees will be more forthcoming with the attendance policy is yet to be seen.
This kind of dishonesty is much more hurtful to your brand than any logo-design misfire.
