After investigating, I used the wrong function:
get_terms(); using this spits out ALL tags that are defined.
To list all Tags used by a SINGLE post one must use get_the_terms();

So the final code:

// Get Tags

$args = array (
    'taxonomy' => 'newstags',
    'orderby' => 'name',
    'order' => 'ASC',
);

$tags = get_the_terms($post, 'newstags');
if ( !empty($tags)  ) :
foreach ( $tags as $tag ) {
    $tag_link = esc_url( get_tag_link( $tag->term_id ) );
    $html = '<span id="news-pill" class="badge badge-pill badge-secondary"><i class="fas fa-tag"></i> ';
    $html .= "<a href='{$tag_link}' title='{$tag->name} Tag' class='{$tag->slug}'>";
    $html .= "{$tag->name}</a></span>";
        echo $html;
}
endif;

Solved it. This works for me:

<?php
// Get Tags
$args = array (
    'taxonomy' => 'newstags',
    'orderby' => 'name',
    'order' => 'ASC',
);

$tags = get_terms($args);
foreach ( $tags as $tag ) {
    $tag_link = esc_url( get_tag_link( $tag->term_id ) );
    $html = '<span id="news-pill" class="badge badge-pill badge-secondary"><i class="fas fa-tag"></i> ';
    $html .= "<a href='{$tag_link}' title='{$tag->name} Tag' class='{$tag->slug}'>";
    $html .= "{$tag->name}</a></span>";
    if ( !empty($tags)  ) :
        echo $html;
    endif;
}

Thanks anyway for your simple yet awesome plugin ??
