They're not annoyed that the post mentions VSCode. They're annoyed that, from their experience, only VSCode is being supported.

VSCode is the only integration that the Deno core team maintains and develops. A rough poll indicates that about 80% of Deno users use vscode.

JetBrains/WebStorm now utilises the Deno language server directly (the same one that the VSCode integration uses) but they control how features are expressed in their client and when they deliver them, something the core team can't directly control.

So for various reasons, VSCode ends up being the focus.
