Vlad helped me troubleshoot why my Orion browser wasn't syncing bookmarks (turned out to be a config issue on my device) and we got the fix added into the official documentation.
Imagine getting that level of support for any other web browser!
If I notice something is wrong I can report it and expect to have a developer look into it within reasonable time.
They are grateful for reports from users and if there is an actual problem (and not a misunderstanding) it is also fixed, again with a reasonable.
(The first major reason for me is premium search quality, no tracking probably comes at a distant third or something.)
