With respect to the standard parts idea... I'm not sure what that means.
Inside an Oppo player (or basically any disk player) There is a power supply, several circuit boards, a laser mechanism, and a motorized loading drawer. The chassis is not a standard part. The power supply is not a standard part. And the PC boards are not standard parts. Certainly, included on those assemblies are manufactured chips and such that are purchased from other manufacturers and they may be used across many different manufacturers product lines, but the boards themselves are not "standard". They are engineered and designed by Oppo and contracted out to be built by a third party. Servicing a disk player in 2018 means testing and replacing a defective board, since it is just too expensive labor-wise (and talent-wise) to troubleshoot an electrical problem at the component level, even though this was regularly done back in the 70s and 80s. Todays electronics are so much more disposable.
So that leaves the laser mechanism and the motorized drawer. And I can see these items being considered "standard". But then again, they are probably "standard" for a lot of brands in the same way with several manufacturers using the same laser mechanism. Maybe electronic giants like Sony have the ability and financial backing to produce their own "standard" parts, and they may sell them to others or keep them proprietary. Pioneer was at one time the only manufacturer of the disk loading assemblies that had only a slot and no drawer. They appeared in a lot of different products.
I guess there is some logic in thinking that since an Oppo uses off the shelf laser assemblies, and since those assemblies appear in a lot of other brands, they would tend to have higher demand and may be available longer. Sure. I just don't know how different it is from the way other brands manufacture their products.
