Usually general business models are not protected as intellectual property in the same way as bit-for-bit copies in the case of mp3s/writings. I’m not saying it should be.

The bigger issue that you are pointing to is that the tech companies are becoming large trusts that do everything and can leverage their size to win everywhere. E.g. see Amazon competing with Intel now.

The anti-trust movement needs to be stronger if society says: ‘wait, this isn’t a good idea to let one company win at everything’
