I don't think this is entirely true. If you do not have your apple product serviced at an apple-authorized repair center, then you void your warranty and risk being refused future repair service by Apple. In a sense, they are pretty similar to what Nikon wishes to be. Although, technically speaking, Nikon is not forbidding the 3rd party repair, they are just making it very hard (or virtually impossible) for a 3rd party repair center to be viable since they are cutting off the supply of parts.
However, you are correct in that there still are 3rd party alternatives you can fall back on, like replacement laptop batteries, even things like screens I believe can be purchased.
