They dropped support for legacy extensions that were arguably more powerful than the new content blocking framework which is basically a list of links bundled as an app.
For example, a popular ad blocker uBlock Origin no longer works on Safari 13. Read here for explanation and recommendations.
uBlock Origin was ported for Safari in 2016, and was updated regulary (mostly changes from the main project) until 2018 when development completley stopped. Since then Apple has begun phasing out Safari extensions as extensions, and has instead been implenting a new extensions framework which is extremley limited in adblocking functions, only allowing "content blockers", which are just links bundled as an app which Safari enforces. From Safari 12 / macOS Mojave, old legacy Safari extensions were still allowed, but came with warnings saying that they will slow down your browsing (they infact won't, or at least not noticably). Safari also recently shut their Extension Gallery, instead redirecting it to the mac app store. Though it is still curently possible to install uBlock Origin by downloading the extension from Github (edit: must follow these instructions, it will not be starting from Safari 13 / macOS Catalina, when the legacy entension API will be fully deprecated.
