The PDF icon shows the Adobe Acrobat "cursive A," which is entirely vendor-specific.
Adobe relinquished control of PDF in 2007 and PDF has been an international ISO standard since 2008 (as ISO 32000). Its icon should reflect this vendor- and platform-neutral position, as there are literally hundreds of PDF viewers available. This icon library should not be promoting one specific commercial vendor.
For example, see https://microsoft.github.io/vscode-codicons/dist/codicon.html or Font Awesome for vendor-neutral PDF icons (e.g. just use the acronym "PDF" in front of a curled corner page).
