Maybe you're exaggerating.
That's quite a stretch. What T10 did was completely dishonest. They relied on what a player base knew from the a previous title / feature, sold them and in the end it was not the same thing. This is not. Also, we know how the feature works and it has been used already.
You could complain about PD not having predicted the load of the servers because of these features being postponed (the 4 ones from the article) but 3 of them, we already used during the demo and the import decals was probably used during the event PD held 2 months ago on their HQ for the gaming media - they had their logos ingame to test the livery feature.
I prefer they focus during these 2/3 days on the online stability for the actual racing and fix the issues that can come around and then unlock the social features / import decal. Sure, everything should be working day one, but I prefer this than to have everything available with game braking bugs (as it happened with PC2 and got me pretty frustrated for example).
