Australian government unveils 'world-leading' regulation of tech giants

> Under the direction of Treasurer Josh Frydenberg, the unit's first priority will be inquiring into the tech companies' advertising technology and algorithms.

This seems like a weird thing to focus on. What exactly are they looking to find out? It's not like it's the advertising algorithms that are at fault, its the content of the ads that's the problem as we've seen by the content of the Conservative party's ads in the UK election (who use the same PR company as the current Australia government)

Anyone know how any of this is actually enforceable?
