Agreed, I'm having a hard time seeing how this is anti-competitive. It sounds like they're just saying that tech giants are competing very successfully by virtue of being really big and having lots of money. Paying people really well, buying out startups with good tech, competing with startups, etc.; none of that sounds illegal, or even unethical.
There's also an argument to be made that big tech giants have some benefits for startup ecosystems. The option of being bought out, for example, acts as a safety net, so that even if your company doesn't have explosive growth that lets it go public, well at least you'll get something out of it. Similarly, having tech giants nearby means that even if your startup just implodes, you can probably still get a decent job in the area (going from big company to startup to back again is really common in the bay area, for example).
