Why no FLAC support on recent Blu-Ray devices?

I've been watching recent releases of Blu-Ray players and most of them just ignore lossless formats like FLAC, WavPack and so on.
They ship with MP3 and some are shipping with AAC support, but FLAC is a dream...

Any logic reason besides contractual ties with proprietary formats?

Incidentally, the reason so many of these devices won't support gapless decoding is that the company in question would have to actually license the source code to add the feature, and they generally don't want to pay to do that. Unsurprisingly, Apple was one of the earlier companies to start doing full gapless decoding, since they already owned the decoder source code it didn't cost them anything beyond some programmer's time.

Could you explain that in more detail?
I thought gapless playback was simply a matter of programming (perhaps adding a bit of buffering or whatever..). How does licensing come into play?

Programming requires source code. If you just buy a binary decoder, you can't change it, and so its not really possible to add new features (at least without extraordinary effort anyway).
