Bundling stuff is an attempt to limit competition. Similar to making it difficult for others to manufacture things which work with your product (as non standard extenstions, parts etc.) It's not a problem if it's easy to shop around but once you do it from dominant market position it becomes abuse. Prime example is bundling cell phones with contracts in US. The world would be better place (well, at least for consumers) if that was banned. If banning things leads to good outcomes it's one justification to make it a law. That's the way anti-monopoly laws came about.
