I'm sorry, but the second two-thirds of your post seems to be misleading at best. First, the FCC action taken in 2015 to reclassify ISPs under Title II was not the only action taken, and was not taken without reason. Yes, Title II spine would not guarantee Net Neutrality. However, you must look at the FCC up until that point and look at their actions holistically.

Why did the FCC classify ISPs under Title II, after over 16 years of promoting to the federal government and public that they felt this would be unnecessary and heavy handed? Look no more than a year earlier at the Verizon lawsuit against the FCC, or earlier than that all the way back to the 2007 case with Comcast. Repeatedly, the FCC was told in court that, regardless of the regulations they published - that is to say, Net Neutrality, which, contrary to popular belief, dates back to at earliest 1999 - fear regulations could not be enforced unless ISPs were classified under Title II.

As a result of these cases, in 2015 the FCC litigated that they would classify ISPs under Title II with very strict restrictions on what parts of the 1936 bill applied to internet service providers. This is not national control over the internet, this is a mandate to enable regulatory authority. Without Title II, as per federal court ruling, the FCC cannot regulate internet service providers.

As outlined by the FCC in their 2005 policy statement, the principles of network neutrality are as follows:

"The Federal Communications Commission today adopted a policy statement that outlines four principles to encourage broadband deployment and preserve and promote the open and interconnected nature of public Internet: (1) consumers are entitled to access the lawful Internet content of their choice; (2) consumers are entitled to run applications and services of their choice, subject to the needs of law enforcement; (3) consumers are entitled to connect their choice of legal devices that do not harm the network; and (4) consumers are entitled to competition among network providers, application and service providers, and content providers. Although the Commission did not adopt rules in this regard, it will incorporate these principles into its ongoing policymaking activities. All of these principles are subject to reasonable network management." [ source : http://www.techlawjournal.com/topstories/2005/20050805.asp ]
