”Do I have to pay to use BBEdit?

No. You can use BBEdit without purchasing a license, in the same way you’ve been using TextWrangler (yes, for free). If you want BBEdit’s complete feature set (web authoring tools, and other exclusive features), you can purchase a license any time you like.”

They also claim that gives you more than TextWrangler’s feature set (https://www.barebones.com/products/bbedit/comparison.html). If they didn’t add nagging for upgrades, it seems they simply renamed TextWrangler to BBEdit.
