@HotCakeX This happened because the original creator of uBlock Origin did not support Microsoft Edge (Legacy) and had no plans to port it at the time. Nik forked it and made changes to make it run on Edge. He was able to release his version to the store and kept it up-to-date for awhile but it sounds like he got very busy and it became difficult for him to keep up.
Since the store is registered in Nik's name for the Edge (Legacy) store, that is what carried over to the new extension store. There were some talks about giving Raymond Hill store access in Nik's repo at
It sounds to me that it mostly is between them two to figure out how to give Raymond access to push his own changes. Maybe they need help from Microsoft to sort it out.
Another guy, jspenguin2017, also forked uBlock Origin in general and created Nano Adblocker. This version added support for Edge (Legacy) with a compatibility shim that made it easier to keep up-to-date with latest changes from uBlock without too much work. He has dropped support for Edge (Legacy) now that the new Edge has reached stable.
When I saw this on Reddit earlier this month, I passed it on to the team. They are trying to figure out what happened here and how we can make this right. Still don't have any info on this, but this reminds me to follow up. Thanks, HotCake! :3
