Question
How to edit the Drupal 8 system's "Powered By" block ?
You can't change the body of this block fron the user interface. But you can do that using a small custom module using hook_block_view_alter().
Example: in the yourmodule.module
function yourmodule_block_view_alter(array &$build, \Drupal\Core\Block\BlockPluginInterface $block) {
if ($block->getBaseId() === 'system_powered_by_block') {
$build['#pre_render'][] = '_yourmodule_block_poweredby_prerender';
}
}
function _yourmodule_block_poweredby_prerender(array $build) {
$build['content']['#markup'] = 'Your text';
return $build;
}
Then clear the cache
NOTE: You can also remove the system 'Powered by Drupal' block and replace by a custom block.
