Announcing the Fabric Community
OK Fabric is great but is not available to most Power BI users so not relevant to most of the audience here. You have created a lot of confusion by hijacking the Power BI community with it's years of content, and re-branding it as "Fabric". A separate Fabric community should've been established for those topics.
You should consider the experience of a new or novice user. Power BI free and Pro licenses are their gateway into perhaps scaling up to Fabric some day. But now it looks like Power BI doesn't exist - everything is Fabric. When they look at the cost of Premium + Fabric, most will get sticker shock and consider cheaper options from other vendors.
You clearly rushed this change as once you start using the community site, "Fabric" often does not appear on the pages, topics etc. Can you just press "undo" on this and revert to the Power BI community, with a separate community for Fabric?
