Rather than believe something nefarious, I believe that is just Ukraine restricting possible leaks about its counteroffensive, which may or may not have begun.

Ah yes, The Intercept, founded by blatant Russian propagandist and "Ukraine had biolabs" conspiracy promoter Glenn Greenwald. Surely this article is unbiased and not at all misleading.

tl;dr:

Some Ukrainian journalists have also warned that military handlers' tight oversight of journalists is skewing coverage of the war. The Ukrainian military doesn't have a formal embed system - the process by which war journalists cover conflicts by tagging along troops in the field - and most press access consists of short, chaperoned visits to military positions further back than the actual front lines. As a result, stories about the front lines are often told by journalists visiting recently liberated areas or as secondhand accounts relayed by military leadership. Many of the journalists whose credentials were revoked more recently had at some point worked in Russian-held territories, sometimes as far back as 2014, when Russia first invaded Crimea and parts of eastern Ukraine. In May, military authorities also canceled all existing credentials and made journalists apply for new ones; several journalists said their new credentials were denied.

I am a bot in training. Suggestions?

"Ukraine calls for media silence ahead of counteroffensive"

Media: can we broadcast form the front lines?

Ukraine: no?

Media: surprised Pikachu face

Seems reasonable when you are on the offensive

“It’s wild how little of what’s happening is being chronicled,”

Sorry Putin, Ukraine will not tell you its military plans!
