The opinion when this came up on /r/europe was that it was an attempt at clamping down on access to independent and non-Hungarian media by making internet use unaffordable.
Edit: well, that seems comprehensively debunked

I mean, you get free press (Metropol, elsewhere known as Metro, which IIRC is swedish) at metro stations, it would make more sense to tax _that_ if you really wanted to clamp independent media.
Also, many people with a smartphone aged 25+ have a company-payed one, so the tax is irrelevant to them. (source: anecdotal evidence as someone living in hungary)
What if the tax is just a trojan horse? If it's introduced, the government will have to install "smart meters" somewhere, checking who consumed what in order to reconcile it with the amount of paid tax. The move from "smart meters" to "total eavesdropping capability" is then just a firmware update away.
If you really think the political news/anything ratio is higher in the average megabyte of internet download than in Metro I am afraid you live in a very unusual bubble.
Purchase a modern AAA game on steam, they're around 30G. Instant 15e additional tax when downloading it. And that tax gets paid every time you redownload anything.
Also netflix becomes a lot more expensive. 50 cents per hour for standard definition or 1.5 euros per hour in HD.
