Node was something new, that hadn't been done before and was easy to use, it meant that you could use Javascript on the front and backend, so you didn't need people with experience in PHP/Java/C# to write your backend code. You could reuse functions.

But when Deno came out, it was basically seen as an improvement on Node that wasn't entirely compatible with it. You couldn't just switch `node run` to `deno run` and have it work. Node has the critical mass of modules that Deno doesn't, and people already have a lot of experience with Node.

Basically, people just think Node is good enough and Deno doesn't offer enough to bother switching.
