This is all about the money. By assigning ISPs to Title II it becomes possible to tax Internet access immediately. The timing of these actions is a strong indicator. In September 2015 the Internet Tax Freedom Act will expire. It is a temporary law that must be renewed in order to remain law. On July 15, 2014 the House (with limited democrat support) passed the Permanent Internet Tax Freedom Act in an effort to make the law permanent. But it died in the Senate without a vote. The bill has been reintroduced this year but like its predecessor, is considered unlikely to be passed.
Without the Internet Tax Freedom Act, Federal, State, and Municipal governments can tax individuals for all kinds of internet access: access tax, per bit tax, bandwidth tax, franchise tax, even email tax. The pending death of the Internet Tax Freedom Act has been intentionally kept very quiet while the focus and rhetoric revolves around the FCC's "net neutrality" policy proposition. The Internet Tax Freedom Act is obviously very popular with the people. But the key is that unfortunately, the Internet Tax Freedom Act, as it is currently written, cannot prohibit certain very specific transmission and telecommunications taxes if the FCC designates ISPs as utilities under Title II.
Once the FCC starts classifying ISPs as utilities, it will be possible for Federal, State and Municipal governments to slap on the same already-in-place utility and telecommunications taxes that are already charged on telephone lines, power transmission lines, etc. regardless of the status of the Internet Tax Freedom Act. This is the true reason for the reclassification of ISPs to Title II. In other words, governments that charge a tax on telephone and power transmission won't have to pass any additional (unpopular) laws to tax internet in the same way they tax utility access. Once ISPs are classified as utilities, many of the tax laws that are already on the books will be applicable to internet access.
It's actually pretty simple: The government wants more revenue and sees the ISPs growing and making money. They see less and less revenue from taxing telephone landlines, but see an explosion of internet access and activity. Just like the old telephone and power companies - they want more than just the income taxes - they want a much bigger slice of the pie, and the authority to control it. This reclassification will cost the consumer more and does nothing to promote market competition. Moreover, if Congress doesn't make the Internet Tax Freedom law permanent, then its just a matter of time before we see massive taxes on internet access in multiple forms from multiple government entities. Classifying ISPs as utilities is just the tip of the iceburg.
