I am a bit stuck here, what do you call smaller businesses? Rolling out effective targeted advertising is hard in the first place. It's even more so in an environment like Europe where potential buyers are fragmented across countries with different languages, cultures, and so on.
If anything, effective privacy laws levels the playing field. That's good for companies that can't afford a large marketing budget.
