Right, especially if we're looking at launch firmware.
To be honest, the problem isn't even so much that the functionality isn't in the shipping or Day 1 firmware, or that it may not come for a number of months.
The problem is that the FAQ was specifically worded in such a way that it made it sound like the issue was done and finished and the answer was "Nope, you're not getting DLNA and you're not getting MP3s, here's Music Unlimited instead - subscribe or no music for you."
Pile on top of that that asinine contest about Music Unlimited posted on the EU Blog and it doesn't take a rocket scientist to see that it's an absolute tone-deaf way to approach this issue.
There wouldn't have been nearly any outcry if the FAQ had simply said, "Not at launch but in a future firmware," which it did say for certain things, but didn't say that for DLNA or MP3 playback, so why the discrepancy? I don't doubt your sources, but I can't imagine the language in the FAQ wasn't parsed enough to realize that wording would be a problem. If it was just overlooked whoever apparently just recently got promoted in the PR department in Sony needs to be demoted back to wherever they came from because they're completely screwing up the company's messaging with weeks to go until launch.
