Careful what you read. Commercial discs are pressed and don't use any kind of dye. There is a lot of misinformation out there.
I'm going to let Luke speak for himself but yes, money had a lot to do with it. Pride as well. For instance Sony hates every format JVC and Panasonic invent and vice-versa. Not just the consumer VHS/Beta war but Sony and Panasonic are the biggest broadcast and production format rivals and to this day, there are very few Sony broadcast and pro production formats that Panasonic will use and there are very few Panasonic broadcast and pro production formats that Sony will use. Make not none with the exception of a few formats they co-invented.
Back to consumer formats, take Panasonic's DVD-RAM format. Sony is capable of making burners that will write/read RAM as seen in the PIO/Sony recorders but the Sony branded deck's firmware does not allow to write DVD-RAM, (it will read DVD-RAM.) Instead the Sony deck has that much memory space in the firmware for other things. The only reason Sony did this is so they don't have to use a Panasonic format (the licensing fee can't be that high but the pride is. Other manufactures decision is strictly money related.
