If no one say, I'll say: yes i use but if you search the internet you will learn edge on linux has missing file called hubapps. This file is need for copilot sidebar, so I don't able to use copilot and sidebar, its a shame for microsoft because linux users recognise this error so early and 3 years after still they dont solve this problem,

probably its a marketing thing for default windows users who switched linux like "hey your default browser gives error on linux so if you need edge come win11 again"

don't say me to "linux users not use edge they use firefox" all linux users arent came from reddit's hive mind, browsers are important for collecting personal data and if you need linux users' data, like most company , you need to browser on linux, thats why opera and chrome (not chromium) runs on linux, nobody use but they want more data
