Snippet remove btn-mini (category, tag, etc.) outdated

One year ago a snippet was provided by rdellconsulting:

//Remove meta-tag buttons
add_filter('tc_category_list', 'rdc_category_list');
function rdc_category_list($output) {
return preg_replace('"btn btn-mini"', '""', $output);
}

add_filter('tc_tag_list', 'rdc_tag_list');
function rdc_tag_list($output) {
return preg_replace('"btn btn-mini btn-tag"', '""', $output);
}

also listed at the official page: Remove categories and tags buttons in the post metas block

This seems not to work anymore. Found in Customizr hooks API:

tc_category_list_class [filter]
Class attribute of the hierarchical taxonomy terms link (button)
Value / type : btn btn-mini
# of filter parameter(s) : 1

tc_tag_list_class [filter]
Class attribute of the non-hierarchical taxonomy terms link (button)
Value / type : btn btn-mini btn-tag
# of filter parameter(s) : 1

Source code : inc/parts/class-content-post_metas.php

This seems to be an example of usage with Customizr 3.2+: Customizing the comments in the Customizr theme.
I’m too inexperienced in PHP and WP API to get it myself. Thanks for any help.
