This is from quite a bit earlier in 2017. It is just a USA thing, Congress overturned FCC privacy rules, so now internet service providers in the USA are allowed to sell their subscribers' browsing data to third parties.

(Edit: Amazingly the four previous people who responded to you seem to have all gotten it wrong)

Just like with the NSA wiretapping, if you’re not a US citizen you don’t count for much (not that it protected US citizens very much).

Your data has probably been sold a hundred time over already by US companies.

Do you use any websites located in the US? What if they close down?

It potentially reduces the ability for new web companies to succeed in reaching US consumers. It will also enable ISP's to extort existing web companies and lead to higher prices for consumers.

A quick internet search should sort this out for you. It's been articulated ad nauseum
