As others have stated, the rollout of Applied Filters breaks years (decades?) of best practices within SharePoint from Microsoft's own guidance. This is something that should have been opt-in, not opt-out from the beginning, and we definitely need an option to hide this feature as we've previously done for many, many years.
If things are changing this much with the products, it will be hard to find much faith in the future of Microsoft's projects - it seems like literally anyone can suggest a change, do it, and not care about what it breaks in the process. That level of disruption rarely works well in any organization. It certainly doesn't bode well for SharePoint developers, who have been some of the most faithful MS evangelists for a long time now.
