First and foremost, no one can deny the fact that Shroyer clearly violated the terms of his legal promise not to engage in disruptive behavior near the Capitol. In addition, being a journalist doesn't clear you of wrongdoing when you use a megaphone to mobilize angry rioters who then attack a government seat of power. This has nothing to do with politics and everything to do with law and common sense justice.
This prison sentence is politically motivated, and no plea agreement or legal jargon can change that fact. The entire sentencing document is filled with Judge Kelly's perspectives about Shroyer's speech — speech that is undoubtedly protected by the First Amendment. The government didn't care about Shroyer's bullhorn or rowdy people walking into the Capitol, they cared about stopping InfoWars coverage of the 2020 election. This is an authoritarian and dangerous ruling.
