The BBC is required to maintain "balance" over political issues.
Should Google return the same results to all queries (ie no search bubble allowed?)
Should Facebook (indeed any advertiser) be required to serve the same advert no matter what the profile of the incoming request? I mean Billboards are public broadcasts not private to me, why should online advertising be different? I know it is but that's not the point.
I support net neutrality as it is commonly defined, but I think there are many other "neutrality" issues that we gloss over happily. I doubt very much Google will be happy removing the search bubble, and I would be interested in how much it affects the quality of results.
