It's easy to be critical in hindsight but honestly when Deno first came out it was pretty incredible. Even the whole idea about URL based imports makes lots of sense but it was incompatible with any of the existing toolchains that were wildly popular. At the same time, companies like Vercel launched a new kind of framework and leveraged that into a hosting business with I would say great success. They captured developers where they were at _today_, including acknowledging the demographics, the tools, the culture, etc.
