"We are looking to migrate to pure static site generators in the future but WordPress has been an essential tool for us to launch products and share updates with the community."
It's totally routine for businesses to deploy Wordpress or Drupal without giving any prominent credit to those projects. GNU/Linux distributions include hundreds of pieces of other people's software in their branded product, nobody bats an eyelid. It's totally normal for web apps like Mastodon to include upstream components without users being any the wiser. What is it about @purism that makes some people so keen to bash them for doing the same?
