The same is true for the 2nd amendment.
Guns don't have rights, people do.
You have the right to keep and bear arms, and you have the right to publish.
Look at what Thomas Paine was able to do with a simple pamphlet like Common Sense.
if we are guaranteed freedom of the press, why are conservative voices severely curtailed?
The right to own a press (like the right to own a gun), doesn't obligate one to use it for public good. If one wants to be protected, one doesn't rely on his neighbor's gun, he gets his own.
If one wants his opinions heard, he can't rely on his neighbor's printing press, he has to get his own.
Today, this has been replaced with blogging. Letters to the editor are now comments sections in articles (this is an example of using someone else's press -- they can shut off the comments if they want).
Somebody invented Facebook, somebody invented Twitter. Sure, they've become subverted, but they are modern examples of freedom to publish, and they've become modern examples of partisan press, like the National Gazette and Gazette of the United States were in the 1790s.
"Why are conservative voices severely curtailed?" Because nobody has stepped up to create a friendly partisan platform to rival the others. Some are trying now, but how long did it take Facebook and Twitter to reach the critical mass it has today?
In the meantime, we have resources like FreeRepublic, and blog technology to form individual sites like American Thinker, Townhall.com, Conservative Treehouse, Allahpundit, Newsmax, Gateway, etc.

The problem is, if GoogleGoebbels, Facebooger, Twatter, Instagrim, etc. are engaging in predatory or unfair competitive practices (I’ve hears of Facebook and Amazon being quite bare-knuckes and cut-throat in nature), while getting breaks from the government, it can be mighty difficult to create a competing conservative giant. Plus, at least some of these companies enjoys the Section 283 (?) public platform agreement with the US government that limits their ability to censor, especially when it comes to political posts. They seem to be ignoring that agreement.
That’s why there are calls for action on this forum, although such may seem to contradict conservatism at first blush.
Meanwhile, Gab actually acts like a publisher, but lets people say practically anything they want, including throwing out N-bombs and spreading anti-Semitic tropes. Go figure.
