5MW/H is different than 5MW.
One is a rate, the other is a charge.
To help understand the difference-- A bucket holds 5 gallons. A firehose delivers 5 gallons per second.
Concerning the resale of personally identifiable information to "interested 3rd parties", they get around it by "anonymizing" and "obfuscating" the information, so that it is not "personally identifiable" anymore. Except of course, that the interested 3rd party is hoovering in that data like a ravenous black hole, and doing everything possible to undo that obfuscation and anonymization. This makes it a "*nod, wink* yes, totally not personally identifiable! totally!" practice to sell that information.
Really, the actual solution is to make the practice of de-anonymizing information illegal, except for law enforcement, with more than just token wrist-slap punishments.
As is, trying to use the VPN route to further obscure your identity so your ISP cannot sell anything useful is only going to pressure the industry toward deep packet inspection and aggressive decryption of user data, so they can circumvent your clearly intentional efforts to avoid being identified. That is what will happen as computational capacity becomes more and more available/cheap. It is the WRONG direction.
To solve the problem, you have to solve the problem: It is highly profitable to personally identify individual people for targeted advertisements.
We have to make it NOT profitable. ONLY THEN will it stop being a highly aggressively sought "holy grail" of marketing with strong industry pressure to make a reality. You do that with astoundinly heavy fines. The kind that make the moon landing look like a thrifty discount operation.
